  "details": "libcurl can in some circumstances reuse the wrong connection when asked to do\nan Negotiate-authenticated HTTP or HTTPS request.\n\nlibcurl features a pool of recent connections so that subsequent requests can\nreuse an existing connection to avoid overhead.\n\nWhen reusing a connection a range of criterion must first be met. Due to a\nlogical error in the code, a request that was issued by an application could\nwrongfully reuse an existing connection to the same server that was\nauthenticated using different credentials. One underlying reason being that\nNegotiate sometimes authenticates *connections* and not *requests*, contrary\nto how HTTP is designed to work.\n\nAn application that allows Negotiate authentication to a server (that responds\nwanting Negotiate) with `user1:password1` and then does another operation to\nthe same server also using Negotiate but with `user2:password2` (while the\nprevious connection is still alive) - the second request wrongly reused the\nsame connection and since it then sees that the Negotiate negotiation is\nalready made, it just sends the request over that connection thinking it uses\nthe user2 credentials when it is in fact still using the connection\nauthenticated for user1...\n\nThe set of authentication methods to use is set with `CURLOPT_HTTPAUTH`.\n\nApplications can disable libcurl's reuse of connections and thus mitigate this\nproblem, by using one of the following libcurl options to alter how\nconnections are or are not reused: `CURLOPT_FRESH_CONNECT`,\n`CURLOPT_MAXCONNECTS` and `CURLMOPT_MAX_HOST_CONNECTIONS` (if using the\ncurl_multi API)."

  "details": "This flaw allows an attacker to intentionally inject cookies into a running\nprogram using libcurl, if the specific series of conditions are met.\n\nlibcurl performs transfers. In its API, an application creates \"easy handles\"\nthat are the individual handles for single transfers.\n\nlibcurl provides a function call that duplicates an easy handle called\n[curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html).\n\nIf a transfer has cookies enabled when the handle is duplicated, the\ncookie-enable state is also cloned - but without cloning the actual\ncookies. If the source handle did not read any cookies from a specific file on\ndisk, the cloned version of the handle would instead store the filename as\n`none` (using the four ASCII letters, no quotes).\n\nSubsequent use of the cloned handle that does not explicitly set a source to\nload cookies from would then inadvertently load cookies from a file named\n`none` - if such a file exists and is readable in the current directory of the\nprogram using libcurl, when using the correct file format of course."

  "details": "curl supports SFTP transfers. curl's SFTP implementation offers a special\nfeature in the path component of URLs: a tilde (`~`) character as the first\npath element in the path to denotes a path relative to the user's home\ndirectory. This is supported because of wording in the [once proposed\nto-become RFC\ndraft](https://datatracker.ietf.org/doc/html/draft-ietf-secsh-scp-sftp-ssh-uri-04)\nthat was to dictate how SFTP URLs work.\n\nDue to a bug, the handling of the tilde in SFTP path did however not only\nreplace it when it is used stand-alone as the first path element but also\nwrongly when used as a mere prefix in the first element.\n\nUsing a path like `/~2/foo` when accessing a server using the user `dan` (with\nhome directory `/home/dan`) would then quite surprisingly access the file\n`/home/dan2/foo`.\n\nThis can be taken advantage of to circumvent filtering or worse."

Therefore potentially revealing sensitive internal information to the\nserver using a clear-text network protocol.\n\nThis could happen because curl did not call and use `sscanf()` correctly when\nparsing the string provided by the application.\n\nThe previous curl security vulnerability\n[CVE-2021-22898](https://curl.se/docs/CVE-2021-22898.html) is almost identical\nto this one but the fix was insufficient so this security vulnerability\nremained."

This rarely used option is used to send variable=content pairs to\nTELNET servers.\n\nDue to flaw in the option parser for sending `NEW_ENV` variables, libcurl\ncould be made to pass on uninitialized data from a stack based buffer to the\nserver. Therefore potentially revealing sensitive internal information to the\nserver using a clear-text network protocol.\n\nThis could happen because curl did not check the return code from a\n`sscanf(command, \"%127[^,],%127s\")` function invoke correctly, and would leave\nthe piece of the send buffer uninitialized for the value part if it was\nprovided longer than 127 bytes. The buffer used for this is 2048 bytes big and\nthe *variable* part of the *variable=content* pairs would be stored correctly\nin the send buffer, making curl sending \"interleaved\" bytes sequences of stack\ncontents. A single curl TELNET handshake could then be made to send off a\ntotal of around 1800 bytes of (non-contiguous) stack contents in this style:\n\n    [control byte]name[control byte]\n    stack contents\n    [control byte]name[control byte]\n    stack contents\n    ...\n\nAn easy proof of concept command line looks like this:\n\n    curl telnet://example.com -tNEW_ENV=a,bbbbbb (256 'b's)"

  "details": "An application that performs multiple requests with libcurl's multi API and\nsets the `CURLOPT_CONNECT_ONLY` option, might in rare circumstances experience\nthat when subsequently using the setup connect-only transfer, libcurl picks\nand uses the wrong connection - and instead picks another one the application\nhas created since then.\n\n`CURLOPT_CONNECT_ONLY` is the option to tell libcurl to not perform an actual\ntransfer, only connect. When that operation is completed, libcurl remembers\nwhich connection it used for that transfer and \"easy handle\". It remembers the\nconnection using a pointer to the internal `connectdata` struct in memory.\n\nIf more transfers are then done with the same multi handle before the\nconnect-only connection is used, leading to the initial connect-only\nconnection to get closed (for example due to idle time-out) while also new\ntransfers (and connections) are setup, such a *new* connection might end up\ngetting the exact same memory address as the now closed connect-only\nconnection.\n\nIf after those operations, the application then wants to use the original\ntransfer's connect-only setup to for example use `curl_easy_send()` to send\nraw data over that connection, libcurl could **erroneously** find an existing\nconnection still being alive at the address it remembered since before even\nthough this is now a new and different connection.\n\nThe application could then accidentally send data over that connection which\nwas not at all intended for that recipient, entirely unknowingly."

  "details": "curl can be tricked by a malicious server to overwrite a local file when using\n`-J` (`--remote-header-name`) and `-i` (`--include`) in the same command line.\n\nThe command line tool offers the `-J` option that saves a remote file using\nthe filename present in the `Content-Disposition:` response header. curl then\nrefuses to overwrite an existing local file using the same name, if one\nalready exists in the current directory.\n\nThe `-J` flag is designed to save a response body, and so it does not work\ntogether with `-i` and there is logic that forbids it. However, the check is\nflawed and does not properly check for when the options are used in the\nreversed order: first using `-J` and then `-i` were mistakenly accepted.\n\nThe result of this mistake was that incoming HTTP headers could overwrite a\nlocal file if one existed, as the check to avoid the local file was done first\nwhen body data was received, and due to the mistake mentioned above, it could\nalready have received and saved headers by that time.\n\nThe saved file would only get response headers added to it, as it would abort\nthe saving when the first body byte arrives. A malicious server could however\nstill be made to send back virtually anything as headers and curl would save\nthem like this, until the first CRLF-CRLF sequence appears.\n\n(Also note that `-J` needs to be used in combination with `-O` to have any\neffect.)"

  "details": "curl can be fooled into writing a zero byte out of bounds.\n\nThis bug can trigger when curl is told to work on an FTP URL, with the setting\nto only issue a single CWD command (`--ftp-method singlecwd` or the libcurl\nalternative `CURLOPT_FTP_FILEMETHOD`).\n\ncurl then URL-decodes the given path, calls strlen() on the result and deducts\nthe length of the filename part to find the end of the directory within the\nbuffer. It then writes a zero byte on that index, in a buffer allocated on the\nheap.\n\nIf the directory part of the URL contains a \"%00\" sequence, the directory\nlength might end up shorter than the filename path, making the calculation\n`size_t index = directory_len - filepart_len` end up with a huge index\nvariable for where the zero byte gets stored: `heap_buffer[index] = 0`. On\nseveral architectures that huge index wraps and works as a negative value,\nthus overwriting memory *before* the intended heap buffer.\n\nBy using different file part lengths and putting %00 in different places in\nthe URL, an attacker that can control what paths a curl-using application uses\ncan write that zero byte on different indexes."

  "details": "libcurl may read outside of a heap allocated buffer when doing FTP.\n\nWhen libcurl connects to an FTP server and successfully logs in (anonymous or\nnot), it asks the server for the current directory with the `PWD` command. The\nserver then responds with a 257 response containing the path, inside double\nquotes. The returned path name is then kept by libcurl for subsequent uses.\n\nDue to a flaw in the string parser for this directory name, a directory name\npassed like this but without a closing double quote would lead to libcurl not\nadding a trailing null byte to the buffer holding the name. When libcurl would\nthen later access the string, it could read beyond the allocated heap buffer\nand crash or wrongly access data beyond the buffer, thinking it was part of\nthe path.\n\nA malicious server could abuse this fact and effectively prevent libcurl-based\nclients to work with it - the PWD command is always issued on new FTP\nconnections and the mistake has a high chance of causing a segfault.\n\nThe simple fact that this issue has remained undiscovered for this long could\nsuggest that malformed PWD responses are rare in benign servers."

This means a hostname of example.com would\nmatch a DNS SAN of `*.com`, among other variations. This approach violates\nrecommendations in RFC 6125 and could lead to MITM attacks."

The curl code for parsing the second *unsigned* number did not check for a\nleading minus character, which allowed a user to specify `[1--1]` with no\ncomplaints and have the latter `-1` number get turned into the largest\nunsigned long value the system can handle. This would ultimately cause curl to\nwrite outside the dedicated heap allocated buffer after no less than 100,000\niterations, since it would have room for 5 digits but not 6.\n\n2.

An easy handle can hold references to one or many such connection\nstructs depending on the requested operations.\n\nWhen using libcurl's multi interface, an application performs transfers by\nadding one or more easy handles to the multi handle and then it can drive all\nthose transfers in parallel.\n\nDue to a flaw, libcurl could leave a pointer to a freed connection struct\ndangling in an easy handle that was previously added to a multi handle when\n`curl_multi_cleanup()` is called with an easy handle still added to it. This\ndoes not seem to cause any notable harm if the handle is then closed properly.\n\nHowever, if the easy handle would instead get used again with the easy\ninterface and `curl_easy_perform()` to do another transfer, it would blindly\nuse the connection struct pointer now pointing to freed memory.\n\nAn application could be made to allocate its own fake version of the connect\nstruct, fill in some data and then have the `curl_easy_perform()` call do\nsomething that clearly was not intended by the original code.\n\nFor example, this could be an application using a component or library that\nuses libcurl to do something against fixed URLs or fixed hostnames or with a\nset of fixed options, but using this flaw the application can then make the\ncomponent to do something completely different and unintended.\n\nPseudo code for a bad application\n\n    easy = curl_easy_init();\n    curl_easy_setopt(easy, CURLOPT_URL, \"http://example.com/\");\n\n    // --- start of code to confuse libcurl ---\n    multi = curl_multi_init();\n    curl_multi_add_handle(multi, easy);\n    curl_multi_perform(multi, &still_running);\n    curl_multi_cleanup(multi);\n\n    // --- attack code\n    allocate_fake_connection_struct()\n    fill_in_fake_connection_struct()\n\n    // ---- end of confusion code\n\n    // now this is called, it will not use example.com at all even if the\n    // option above asks for it...\n\n    curl_easy_perform(easy);\n\nThis flaw can also be exploited using libcurl bindings in other languages."

  "details": "libcurl would load Windows system DLLs in a manner that may make it vulnerable\nto a DLL hijacking (aka binary planting) attack in certain configurations.\n\nlibcurl has a unified code base that builds and runs on a multitude of\ndifferent versions of Windows. To make that possible, when libcurl is built\nwith SSPI or telnet is used, it dynamically loads some of the necessary system\nDLLs at runtime by calling `LoadLibrary()`. No path is specified for these\nDLLs.\n\nTo find a DLL when no path is specified `LoadLibrary()` follows [DLL search\norder](https://msdn.microsoft.com/en-us/library/windows/desktop/ms682586.aspx#search_order_for_desktop_applications)\nto load it. If it is a \"known DLL\" no searching is done, the system copy is\nused. If it is not a \"known DLL\": The application directory is searched first.\nThe current directory is searched next, if DLL safe search mode is not\nenabled. The system directory is searched next.\n\nThe 3 system DLLs libcurl loads dynamically are `security.dll`, `secur32.dll`\nand `ws2_32.dll` (a \"known DLL\" when installed). These DLLs may not be present\non some versions of Windows, which is why they are loaded\ndynamically. Depending on a number of factors outlined in the DLL search order\ndocument it may be possible for an attacker to plant a DLL of the same name in\nthe user's current directory, application directory or other directory in the\nDLL search order, thereby possibly causing it to be loaded first.\n\n**Recent versions of Windows include all 3 of those dynamically loaded system\nDLLs and also enable safe DLL search mode by default. Therefore in such a case\n`ws2_32.dll` could not be planted, and `security.dll` or `secur32.dll` could\nonly be planted in the application directory.**\n\nTo address this issue we have changed libcurl so that any system DLL it\ndynamically loads in Windows is done in the most secure way available.\n\nNote if an attacker has the ability to write new files to your application\ndirectory they can likely still plant DLLs to be loaded in any case, load-time\nor runtime. This is by design in Windows DLL loading (refer the the DLL\nsearch order doc). For example it may be possible to override DLL search paths\nby planting an app.exe.local file or possibly a fake manifest. There is\nnothing we can do to prevent against this. We advise you to guard write\npermissions on your application directory.\n\n**Also note it is may still be possible for planting attacks to be done\nagainst load-time DLLs used by libcurl and the curl tool. This is because\nWindows loads those DLLs and their dependencies without specifying a\npath. There is nothing we can do to fix this, it is endemic in the design of\nWindows. We advise you to guard write permissions on your application\ndirectory.**"

  "details": "libcurl did not check the server certificate of TLS connections done to a host\nspecified as an IP address, or when explicitly asked to use SSLv3.\n\nThis flaw only exists when libcurl is built to use mbedTLS or PolarSSL as the\nTLS backend.\n\nThe documentation for mbedTLS and PolarSSL (wrongly) says that the API\nfunction `ssl_set_hostname()` is used only for setting the name for the TLS\nextension SNI. The set string is however even more importantly used by the\nlibraries to verify the server certificate, and if no \"hostname\" is set it\njust skips the check and successfully continue with the handshake.\n\nlibcurl would wrongly avoid using the function when the specified hostname was\ngiven as an IP address or when SSLv3 is used, as SNI is not supposed to be\nused then. This then leads to that all uses of TLS oriented protocols (HTTPS,\nFTPS, IMAPS, POPS3, SMTPS, etc) allows connections to servers with unverified\nserver certificates as long as they are specified as IP addresses or using\nSSLv3.\n\nBy tricking a libcurl-using client to use a URL with a host specified as IP\naddress only, an application could be made to connect to an impostor server or\nMan In The Middle host without noticing.\n\nNote: PolarSSL is the old name and releases of the library that nowadays is\nknown and released under the name mbedTLS."

  "details": "curl does not sanitize colons in a remote filename that is used as the local\nfilename. This may lead to a vulnerability on systems where the colon is a\nspecial path character. Currently Windows is the only OS where this\nvulnerability applies.\n\ncurl offers command line options --remote-name (also usable as `-O`) and\n`--remote-header-name` (also usable as `-J`). When both of those options are\nused together (-OJ) and the server provides a remote filename for the content,\ncurl writes its output to that server-provided filename, as long as that file\ndoes not already exist. If it does exist curl fails to write.\n\nIf both options are used together (`-OJ`) but the server does not provide a\nremote filename, or if `-O` is used without `-J`, curl writes output to a\nfilename based solely on the remote filename in the URL string provided by the\nuser, regardless of whether or not that file already exists.\n\nIn either case curl does not sanitize colons in the filename. As a result in\nWindows it is possible and unintended behavior for curl to write to a file in\nthe working directory of a drive that is not the current drive (i.e. outside\nthe current working directory), and also possible to write to a file's\nalternate data stream.\n\nFor example if curl `-OJ` and the server sends filename=f:foo curl incorrectly\nwrites foo to the working directory for drive F even if drive F is not the\ncurrent drive. For a more detailed explanation see the 'MORE BACKGROUND AND\nEXAMPLE' section towards the end of this advisory.\n\nThough no known exploit is available for this issue at the time of the\npublication, writing one would be undemanding and could be serious depending\non the name of the file and where it ends up being written."

  "details": "libcurl's function\n[`curl_easy_duphandle()`](https://curl.se/libcurl/c/curl_easy_duphandle.html)\nhas a bug that can lead to libcurl eventually sending off sensitive data that\nwas not intended for sending.\n\nWhen doing an HTTP POST transfer with libcurl, you can use the\n`CURLOPT_COPYPOSTFIELDS` option to specify a memory area holding the data to\nsend to the remote server. The memory area's size is set with a separate\noption, for example `CURLOPT_POSTFIELDSIZE`.\n\nAs the name implies, the data in the specified buffer is copied to a privately\nheld memory buffer that libcurl allocates on the heap. The memory area is\nassociated with the common CURL handle, often referred to as an \"easy handle\".\n\nThis handle can be duplicated by an application to create an identical copy,\nand all the already set options and data is then also similarly cloned and are\nbe associated with the newly returned handle. This also includes the data to\nsend in an HTTP POST request.\n\nThe internal libcurl function that duplicates options from the old handle to\nthe new had two problems:\n\n1. It mistakenly treated the post data buffer as if it was a C string which is\n   assumed to end with a zero byte. `strdup()` was subsequently used to\n   duplicate the post data buffer, and as a post data buffer can both\n   legitimately contain a zero byte, or may not contain any zero bytes at all\n   (including a tailing one), `strdup()` could create a copy that a) was too\n   small b) was too large or c) could crash due to reading an inaccessible\n   memory area. The `strdup()` function of course allocates memory off the\n   heap.\n\n2. After duplication of the handle data, the pointer used to read from when\n   sending the data was not updated. When sending off the post, libcurl would\n   still read from the original handle's buffer which at that time could have\n   been freed or reused for other purposes.\n\nWhen libcurl subsequently constructs the HTTP POST request and includes data\nfor the protocol body it copies data from that pointer using the old size and\nthe old pointer. This makes a read from the wrong place and can lead to\nlibcurl inserting data into the request that happens to be stored at that\nplaces in memory at that time.\n\nWe are not aware of anyone having been able to actually exploit this for\nnefarious purposes, but we cannot exclude that it is possible or even might\nalready have been exploited."

  "details": "By not detecting and rejecting domain names for partial literal IP addresses\nproperly when parsing received HTTP cookies, libcurl can be fooled to both\nsending cookies to wrong sites and into allowing arbitrary sites to set\ncookies for others.\n\nFor this problem to trigger, the client application must use the numerical\nIP address in the URL to access the site and the site must send back cookies\nto the site using domain= and a partial IP address.\n\nSince libcurl wrongly approaches the IP address like it was a normal domain\nname, a site at IP address `192.168.0.1` can set cookies for anything ending\nwith `.168.0.1` thus fooling libcurl to send them also to for example\n`129.168.0.1`.\n\nThe flaw requires dots to be present in the IP address, which restricts the\nflaw to IPv4 literal addresses or IPv6 addresses using the somewhat unusual\n\"dotted-quad\" style: `::ffff:192.0.2.128`.\n\nThis is not believed to be done by typical sites as this is not supported by\nclients that adhere to the rules of the RFC 6265, and many sites are written\nto explicitly use their own specific named domain when sending cookies."
