| CVE-2016-9952 | 2 Haxx, Microsoft | 2 Curl, Windows Embedded Compact | 2024-08-01 | 6.8 MEDIUM | 8.1 HIGH |
| The verify_certificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, makes it easier for remote attackers to conduct man-in-the-middle attacks via a crafted wildcard SAN in a server certificate, as demonstrated by "*.com." | |||||
| CVE-2024-0853 | 1 Haxx | 1 Curl | 2024-05-03 | N/A | 5.3 MEDIUM |
| curl inadvertently kept the SSL session ID for connections in its cache even when the verify status (*OCSP stapling*) test failed. A subsequent transfer to the same hostname could then succeed if the session ID cache was still fresh, which then skipped the verify status check. | |||||
| CVE-2016-3739 | 1 Haxx | 1 Curl | 2024-05-01 | 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-2020-8284 | 9 Apple, Debian, Fedoraproject and 6 more | 29 Mac Os X, Macos, Debian Linux and 26 more | 2024-04-08 | 4.3 MEDIUM | 3.7 LOW |
| A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions. | |||||
| CVE-2023-38039 | 3 Fedoraproject, Haxx, Microsoft | 10 Fedora, Curl, Windows 10 1809 and 7 more | 2024-04-01 | N/A | 7.5 HIGH |
| When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory. | |||||
| CVE-2020-8169 | 4 Debian, Haxx, Siemens and 1 more | 6 Debian Linux, Curl, Simatic Tim 1531 Irc and 3 more | 2024-03-27 | 5.0 MEDIUM | 7.5 HIGH |
| curl 7.62.0 through 7.70.0 is vulnerable to an information disclosure vulnerability that can lead to a partial password being leaked over the network and to the DNS server(s). | |||||
| CVE-2020-8177 | 5 Debian, Fujitsu, Haxx and 2 more | 16 Debian Linux, M10-1, M10-1 Firmware and 13 more | 2024-03-27 | 4.6 MEDIUM | 7.8 HIGH |
| curl 7.20.0 through 7.70.0 is vulnerable to improper restriction of names for files and other resources that can lead too overwriting a local file when the -J flag is used. | |||||
| CVE-2021-22897 | 5 Haxx, Netapp, Oracle and 2 more | 30 Curl, Cloud Backup, H300e and 27 more | 2024-03-27 | 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-2021-22898 | 6 Debian, Fedoraproject, Haxx and 3 more | 12 Debian Linux, Fedora, Curl and 9 more | 2024-03-27 | 2.6 LOW | 3.1 LOW |
| curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol. | |||||
| CVE-2021-22901 | 5 Haxx, Netapp, Oracle and 2 more | 34 Curl, Active Iq Unified Manager, Cloud Backup and 31 more | 2024-03-27 | 6.8 MEDIUM | 8.1 HIGH |
| curl 7.75.0 through 7.76.1 suffers from a use-after-free vulnerability resulting in already freed memory being used when a TLS 1.3 session ticket arrives over a connection. A malicious server can use this in rare unfortunate circumstances to potentially reach remote code execution in the client. When libcurl at run-time sets up support for TLS 1.3 session tickets on a connection using OpenSSL, it stores pointers to the transfer in-memory object for later retrieval when a session ticket arrives. If the connection is used by multiple transfers (like with a reused HTTP/1.1 connection or multiplexed HTTP/2 connection) that first transfer object might be freed before the new session is established on that connection and then the function will access a memory buffer that might be freed. When using that memory, libcurl might even call a function pointer in the object, making it possible for a remote code execution if the server could somehow manage to get crafted memory content into the correct place in memory. | |||||
| CVE-2021-22922 | 6 Fedoraproject, Haxx, Netapp and 3 more | 23 Fedora, Curl, Cloud Backup and 20 more | 2024-03-27 | 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-2021-22946 | 8 Apple, Debian, Fedoraproject and 5 more | 37 Macos, Debian Linux, Fedora and 34 more | 2024-03-27 | 5.0 MEDIUM | 7.5 HIGH |
| A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. | |||||
| CVE-2021-22923 | 6 Fedoraproject, Haxx, Netapp and 3 more | 23 Fedora, Curl, Cloud Backup and 20 more | 2024-03-27 | 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-2021-22925 | 7 Apple, Fedoraproject, Haxx and 4 more | 27 Mac Os X, Macos, Fedora and 24 more | 2024-03-27 | 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-2021-22926 | 5 Haxx, Netapp, Oracle and 2 more | 26 Curl, Active Iq Unified Manager, Clustered Data Ontap and 23 more | 2024-03-27 | 5.0 MEDIUM | 7.5 HIGH |
| libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file, it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`), a malicious user can create a file name with the same name as the app wants to use by name, and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake. | |||||
| CVE-2021-22947 | 8 Apple, Debian, Fedoraproject and 5 more | 34 Macos, Debian Linux, Fedora and 31 more | 2024-03-27 | 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. | |||||

| An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only). | |||||
| CVE-2022-27774 | 5 Brocade, Debian, Haxx and 2 more | 17 Fabric Operating System, Debian Linux, Curl and 14 more | 2024-03-27 | 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. | |||||
