| CVE-2023-25690 | 1 Apache | 1 Http Server | 2024-01-02 | N/A | 9.8 CRITICAL |
| Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution. For example, something like: RewriteEngine on RewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P] ProxyPassReverse /here/ http://example.com:8080/ Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version 2.4.56 of Apache HTTP Server. | |||||
| CVE-2022-22720 | 3 Apache, Debian, Fedoraproject | 3 Http Server, Debian Linux, Fedora | 2022-07-25 | 7.5 HIGH | 9.8 CRITICAL |
| Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered discarding the request body, exposing the server to HTTP Request Smuggling | |||||
| CVE-2022-22721 | 3 Apache, Debian, Fedoraproject | 3 Http Server, Debian Linux, Fedora | 2022-07-25 | 6.8 MEDIUM | 9.8 CRITICAL |
| If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier. | |||||
| CVE-2019-10082 | 2 Apache, Oracle | 6 Http Server, Communications Element Manager, Enterprise Manager Ops Center and 3 more | 2022-07-25 | 6.4 MEDIUM | 9.1 CRITICAL |
| In Apache HTTP Server 2.4.18-2.4.39, using fuzzed network input, the http/2 session handling could be made to read memory after being freed, during connection shutdown. | |||||
| CVE-2022-31813 | 1 Apache | 1 Http Server | 2022-07-06 | 7.5 HIGH | 9.8 CRITICAL |
| Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on the origin server/application. | |||||
| CVE-2022-28615 | 1 Apache | 1 Http Server | 2022-07-06 | 6.4 MEDIUM | 9.1 CRITICAL |
| Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may hypothetically be affected. | |||||
| CVE-2022-23943 | 4 Apache, Debian, Fedoraproject and 1 more | 5 Http Server, Debian Linux, Fedora and 2 more | 2022-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions. | |||||
| CVE-2021-40438 | 6 Apache, Debian, F5 and 3 more | 9 Http Server, Debian Linux, F5os and 6 more | 2022-06-14 | 6.8 MEDIUM | 9.0 CRITICAL |
| A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. | |||||
| CVE-2021-39275 | 5 Apache, Debian, Fedoraproject and 2 more | 7 Http Server, Debian Linux, Fedora and 4 more | 2022-06-14 | 7.5 HIGH | 9.8 CRITICAL |
| ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier. | |||||
| CVE-2021-42013 | 4 Apache, Fedoraproject, Netapp and 1 more | 5 Http Server, Fedora, Cloud Backup and 2 more | 2022-06-09 | 7.5 HIGH | 9.8 CRITICAL |
| It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue only affects Apache 2.4.49 and Apache 2.4.50 and not earlier versions. | |||||
| CVE-2021-44790 | 6 Apache, Debian, Fedoraproject and 3 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2022-05-17 | 7.5 HIGH | 9.8 CRITICAL |
| A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. | |||||
| CVE-2021-26691 | 4 Apache, Debian, Fedoraproject and 1 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2022-02-07 | 7.5 HIGH | 9.8 CRITICAL |
| In Apache HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server could cause a heap overflow | |||||
| CVE-2017-7668 | 1 Apache | 1 Http Server | 2021-06-06 | 7.5 HIGH | 9.8 CRITICAL |
| The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value. | |||||
| CVE-2017-3167 | 6 Apache, Apple, Debian and 3 more | 15 Http Server, Mac Os X, Debian Linux and 12 more | 2021-06-06 | 7.5 HIGH | 9.8 CRITICAL |
| In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. | |||||
| CVE-2018-1312 | 5 Apache, Canonical, Debian and 2 more | 8 Http Server, Ubuntu Linux, Debian Linux and 5 more | 2021-06-06 | 6.8 MEDIUM | 9.8 CRITICAL |
| In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection. | |||||
| CVE-2020-11984 | 7 Apache, Canonical, Debian and 4 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2021-06-06 | 7.5 HIGH | 9.8 CRITICAL |
| Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE | |||||
| CVE-2017-7679 | 1 Apache | 1 Http Server | 2021-06-06 | 7.5 HIGH | 9.8 CRITICAL |
| In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header. | |||||
| CVE-2017-9788 | 6 Apache, Apple, Debian and 3 more | 16 Http Server, Mac Os X, Debian Linux and 13 more | 2021-06-06 | 6.4 MEDIUM | 9.1 CRITICAL |
| In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service. | |||||
| CVE-2017-3169 | 1 Apache | 1 Http Server | 2021-06-06 | 7.5 HIGH | 9.8 CRITICAL |
| In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. | |||||
