| CVE-2023-46218 | 2 Fedoraproject, Haxx | 2 Fedora, Curl | 2023-12-24 | N/A | 6.5 MEDIUM |
| This flaw allows a malicious HTTP server to set "super cookies" in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain. | |||||
| CVE-2023-46219 | 2 Fedoraproject, Haxx | 2 Fedora, Curl | 2023-12-24 | N/A | 5.3 MEDIUM |
| When saving HSTS data to an excessively long file name, curl could end up removing all contents, making subsequent requests using that file unaware of the HSTS status they should otherwise use. | |||||
| CVE-2023-28321 | 4 Apple, Fedoraproject, Haxx and 1 more | 13 Macos, Fedora, Curl and 10 more | 2023-08-02 | N/A | 5.9 MEDIUM |
| An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to pattern match, but the wildcard check in curl could still check for `x*`, which would match even though the IDN name most likely contained nothing even resembling an `x`. | |||||
| CVE-2023-28320 | 3 Apple, Haxx, Netapp | 12 Macos, Curl, Clustered Data Ontap and 9 more | 2023-08-02 | N/A | 5.9 MEDIUM |
| A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different backends for resolving host names, selected at build time. If it is built to use the synchronous resolver, it allows name resolves to time-out slow operations using `alarm()` and `siglongjmp()`. When doing this, libcurl used a global buffer that was not mutex protected and a multi-threaded application might therefore crash or otherwise misbehave. | |||||
| CVE-2021-22947 | 7 Apple, Debian, Fedoraproject and 4 more | 30 Macos, Debian Linux, Fedora and 27 more | 2022-07-25 | 4.3 MEDIUM | 5.9 MEDIUM |
| When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server. | |||||
| CVE-2022-32205 | 2 Fedoraproject, Haxx | 2 Fedora, Curl | 2022-07-19 | 4.3 MEDIUM | 4.3 MEDIUM |
| A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method. | |||||
| CVE-2022-32208 | 1 Haxx | 1 Curl | 2022-07-15 | 4.3 MEDIUM | 5.9 MEDIUM |
| When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client. | |||||
| CVE-2022-32206 | 1 Haxx | 1 Curl | 2022-07-15 | 4.3 MEDIUM | 6.5 MEDIUM |
| curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors. | |||||
| CVE-2022-27779 | 1 Haxx | 1 Curl | 2022-06-22 | 5.0 MEDIUM | 5.3 MEDIUM |
| libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would get sent to adifferent and unrelated site or domain. | |||||
| CVE-2022-30115 | 2 Haxx, Netapp | 4 Curl, Hci Bootstrap Os, Hci Compute Node and 1 more | 2022-06-22 | 4.0 MEDIUM | 4.3 MEDIUM |
| Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the HSTS cache. Or the otherway around - by having the trailing dot in the HSTS cache and *not* using thetrailing dot in the URL. | |||||
| CVE-2022-27774 | 1 Haxx | 1 Curl | 2022-06-14 | 3.5 LOW | 5.7 MEDIUM |
| An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are affected that could allow an attacker to extract credentials when follows HTTP(S) redirects is used with authentication could leak credentials to other services that exist on different protocols or port numbers. | |||||
| CVE-2022-27776 | 1 Haxx | 1 Curl | 2022-06-14 | 4.3 MEDIUM | 6.5 MEDIUM |
| A insufficiently protected credentials vulnerability in fixed in curl 7.83.0 might leak authentication or cookie header data on HTTP redirects to the same host but another port number. | |||||
| CVE-2021-22925 | 6 Apple, Fedoraproject, Haxx and 3 more | 10 Mac Os X, Macos, Fedora and 7 more | 2022-06-14 | 5.0 MEDIUM | 5.3 MEDIUM |
| curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application. | |||||
| CVE-2021-22897 | 4 Haxx, Netapp, Oracle and 1 more | 29 Curl, Cloud Backup, H300e and 26 more | 2022-05-13 | 4.3 MEDIUM | 5.3 MEDIUM |
| curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly. | |||||
| CVE-2021-22923 | 4 Fedoraproject, Haxx, Netapp and 1 more | 6 Fedora, Curl, Clustered Data Ontap and 3 more | 2021-12-10 | 2.6 LOW | 5.3 MEDIUM |
| When curl is instructed to get content using the metalink feature, and a user name and password are used to download the metalink XML file, those same credentials are then subsequently passed on to each of the servers from which curl will download or try to download the contents from. Often contrary to the user's expectations and intentions and without telling the user it happened. | |||||
| CVE-2021-22922 | 4 Fedoraproject, Haxx, Netapp and 1 more | 6 Fedora, Curl, Clustered Data Ontap and 3 more | 2021-12-10 | 4.3 MEDIUM | 6.5 MEDIUM |
| When curl is instructed to download content using the metalink feature, thecontents is verified against a hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same contentfrom a set of different URLs, potentially hosted by different servers and theclient can then download the file from one or several of them. In a serial orparallel manner.If one of the servers hosting the contents has been breached and the contentsof the specific file on that server is replaced with a modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload. It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the file ondisk. | |||||
| CVE-2021-22876 | 5 Broadcom, Debian, Fedoraproject and 2 more | 8 Fabric Operating System, Debian Linux, Fedora and 5 more | 2021-07-20 | 5.0 MEDIUM | 5.3 MEDIUM |
| curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request. | |||||
| CVE-2017-2629 | 1 Haxx | 1 Curl | 2019-10-09 | 4.0 MEDIUM | 6.5 MEDIUM |
| curl before 7.53.0 has an incorrect TLS Certificate Status Request extension feature that asks for a fresh proof of the server's certificate's validity in the code that checks for a test success or failure. It ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality. This flaw also exists in the command line tool (--cert-status). | |||||
| CVE-2016-8616 | 1 Haxx | 1 Curl | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password. | |||||
| CVE-2017-1000100 | 1 Haxx | 1 Libcurl | 2018-11-13 | 4.3 MEDIUM | 6.5 MEDIUM |
| When doing a TFTP transfer and curl/libcurl is given a URL that contains a very long file name (longer than about 515 bytes), the file name is truncated to fit within the buffer boundaries, but the buffer size is still wrongly updated to use the untruncated length. This too large value is then used in the sendto() call, making curl attempt to send more data than what is actually put into the buffer. The endto() function will then read beyond the end of the heap based buffer. A malicious HTTP(S) server could redirect a vulnerable libcurl-using client to a crafted TFTP URL (if the client hasn't restricted which protocols it allows redirects to) and trick it to send private memory contents to a remote server over UDP. Limit curl's redirect protocols with --proto-redir and libcurl's with CURLOPT_REDIR_PROTOCOLS. | |||||
| CVE-2017-1000101 | 1 Haxx | 1 Curl | 2018-11-13 | 4.3 MEDIUM | 6.5 MEDIUM |
| curl supports "globbing" of URLs, in which a user can pass a numerical range to have the tool iterate over those numbers to do a sequence of transfers. In the globbing function that parses the numerical range, there was an omission that made curl read a byte beyond the end of the URL if given a carefully crafted, or just wrongly written, URL. The URL is stored in a heap based buffer, so it could then be made to wrongly read something else instead of crashing. An example of a URL that triggers the flaw would be `http://ur%20[0-60000000000000000000`. | |||||
| CVE-2016-3739 | 1 Haxx | 1 Curl | 2018-10-17 | 2.6 LOW | 5.3 MEDIUM |
| The (1) mbed_connect_step1 function in lib/vtls/mbedtls.c and (2) polarssl_connect_step1 function in lib/vtls/polarssl.c in cURL and libcurl before 7.49.0, when using SSLv3 or making a TLS connection to a URL that uses a numerical IP address, allow remote attackers to spoof servers via an arbitrary valid certificate. | |||||
| CVE-2017-1000099 | 1 Haxx | 1 Libcurl | 2017-11-01 | 4.3 MEDIUM | 6.5 MEDIUM |
| When asking to get a file from a file:// URL, libcurl provides a feature that outputs meta-data about the file using HTTP-like headers. The code doing this would send the wrong buffer to the user (stdout or the application's provide callback), which could lead to other private data from the heap to get inadvertently displayed. The wrong buffer was an uninitialized memory area allocated on the heap and if it turned out to not contain any zero byte, it would continue and display the data following that buffer in memory. | |||||
| CVE-2017-9502 | 1 Haxx | 1 Curl | 2017-07-08 | 5.0 MEDIUM | 5.3 MEDIUM |
| In curl before 7.54.1 on Windows and DOS, libcurl's default protocol function, which is the logic that allows an application to set which protocol libcurl should attempt to use when given a URL without a scheme part, had a flaw that could lead to it overwriting a heap based memory buffer with seven bytes. If the default protocol is specified to be FILE or a file: URL lacks two slashes, the given "URL" starts with a drive letter, and libcurl is built for Windows or DOS, then libcurl would copy the path 7 bytes off, so that the end of the given path would write beyond the malloc buffer (7 bytes being the length in bytes of the ascii string "file://"). | |||||
| CVE-2016-0754 | 2 Haxx, Microsoft | 2 Curl, Windows | 2016-02-17 | 5.0 MEDIUM | 5.3 MEDIUM |
| cURL before 7.47.0 on Windows allows attackers to write to arbitrary files in the current working directory on a different drive via a colon in a remote file name. | |||||
