CVE-2022-27779 | 3 Haxx, Netapp, Splunk | 15 Curl, Clustered Data Ontap, H300s and 12 more | 2024-03-27 | 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. | |||||

libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation. | |||||
CVE-2022-30115 | 3 Haxx, Netapp, Splunk | 15 Curl, Clustered Data Ontap, H300s and 12 more | 2024-03-27 | 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-2022-32205 | 7 Apple, Debian, Fedoraproject and 4 more | 29 Macos, Debian Linux, Fedora and 26 more | 2024-03-27 | 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-2022-32206 | 6 Debian, Fedoraproject, Haxx and 3 more | 30 Debian Linux, Fedora, Curl and 27 more | 2024-03-27 | 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-2022-32207 | 6 Apple, Debian, Fedoraproject and 3 more | 19 Macos, Debian Linux, Fedora and 16 more | 2024-03-27 | 7.5 HIGH | 9.8 CRITICAL |
When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended. | |||||
CVE-2022-32208 | 6 Apple, Debian, Fedoraproject and 3 more | 19 Macos, Debian Linux, Fedora and 16 more | 2024-03-27 | 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-2022-35252 | 5 Apple, Debian, Haxx and 2 more | 18 Macos, Debian Linux, Curl and 15 more | 2024-03-27 | N/A | 3.7 LOW |
When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a"sister site" to deny service to all siblings. | |||||
CVE-2022-32221 | 5 Apple, Debian, Haxx and 2 more | 13 Macos, Debian Linux, Curl and 10 more | 2024-03-27 | N/A | 9.8 CRITICAL |
When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously was used to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST. | |||||
CVE-2022-35260 | 4 Apple, Haxx, Netapp and 1 more | 12 Macos, Curl, Clustered Data Ontap and 9 more | 2024-03-27 | N/A | 6.5 MEDIUM |
curl can be told to parse a `.netrc` file for credentials. If that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause a segfault or similar, but circumstances might also cause different outcomes.If a malicious user can provide a custom netrc file to an application or otherwise affect its contents, this flaw could be used as denial-of-service. | |||||
CVE-2022-42915 | 5 Apple, Fedoraproject, Haxx and 2 more | 13 Macos, Fedora, Curl and 10 more | 2024-03-27 | N/A | 8.1 HIGH |
curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0. | |||||
CVE-2023-23914 | 3 Haxx, Netapp, Splunk | 12 Curl, Active Iq Unified Manager, Clustered Data Ontap and 9 more | 2024-03-27 | N/A | 9.1 CRITICAL |
A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality fail when multiple URLs are requested serially. Using its HSTS support, curl can be instructed to use HTTPS instead of usingan insecure clear-text HTTP step even when HTTP is provided in the URL. ThisHSTS mechanism would however surprisingly be ignored by subsequent transferswhen done on the same command line because the state would not be properlycarried on. | |||||
CVE-2023-23915 | 3 Haxx, Netapp, Splunk | 12 Curl, Active Iq Unified Manager, Clustered Data Ontap and 9 more | 2024-03-27 | N/A | 6.5 MEDIUM |
A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. This HSTS mechanism would however surprisingly fail when multiple transfers are done in parallel as the HSTS cache file gets overwritten by the most recentlycompleted transfer. A later HTTP-only transfer to the earlier host name would then *not* get upgraded properly to HSTS. | |||||
CVE-2023-23916 | 5 Debian, Fedoraproject, Haxx and 2 more | 13 Debian Linux, Fedora, Curl and 10 more | 2024-03-27 | N/A | 6.5 MEDIUM |
An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the "chained" HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable "links" in this "decompression chain" wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a virtually unlimited number of compression steps simply byusing many headers. The use of such a decompression chain could result in a "malloc bomb", making curl end up spending enormous amounts of allocated heap memory, or trying to and returning out of memory errors. | |||||

A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system. | |||||
CVE-2023-27534 | 5 Broadcom, Fedoraproject, Haxx and 2 more | 13 Brocade Fabric Operating System Firmware, Fedora, Curl and 10 more | 2024-03-27 | N/A | 8.8 HIGH |
A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. Attackers can exploit this flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a server with a specific user. | |||||
CVE-2023-27535 | 5 Debian, Fedoraproject, Haxx and 2 more | 14 Debian Linux, Fedora, Libcurl and 11 more | 2024-03-27 | N/A | 5.9 MEDIUM |
An authentication bypass vulnerability exists in libcurl <8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not included in the configuration match checks, causing them to match too easily. This could lead to libcurl using the wrong credentials when performing a transfer, potentially allowing unauthorized access to sensitive information. | |||||
CVE-2023-27536 | 5 Debian, Fedoraproject, Haxx and 2 more | 14 Debian Linux, Fedora, Libcurl and 11 more | 2024-03-27 | N/A | 5.9 MEDIUM |
An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can reuse previously established connections with incorrect user permissions due to a failure to check for changes in the CURLOPT_GSSAPI_DELEGATION option. This vulnerability affects krb5/kerberos/negotiate/GSSAPI transfers and could potentially result in unauthorized access to sensitive information. The safest option is to not reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed. | |||||
CVE-2023-27537 | 4 Broadcom, Haxx, Netapp and 1 more | 13 Brocade Fabric Operating System Firmware, Libcurl, Active Iq Unified Manager and 10 more | 2024-03-27 | N/A | 5.9 MEDIUM |
A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free. | |||||
CVE-2023-27538 | 6 Broadcom, Debian, Fedoraproject and 3 more | 15 Brocade Fabric Operating System Firmware, Debian Linux, Fedora and 12 more | 2024-03-27 | N/A | 5.5 MEDIUM |
An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection. |
