| CVE-2021-42013 | 4 Apache, Fedoraproject, Netapp and 1 more | 6 Http Server, Fedora, Cloud Backup and 3 more | 2024-08-04 | 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-2021-41773 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2024-08-04 | 7.5 High |
| A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. 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 is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013. | ||||
| CVE-2021-41524 | 5 Apache, Fedoraproject, Netapp and 2 more | 5 Http Server, Fedora, Cloud Backup and 2 more | 2024-08-04 | 7.5 High |
| While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project. | ||||

| 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 | 7 Apache, Debian, Fedoraproject and 4 more | 14 Http Server, Debian Linux, Fedora and 11 more | 2024-08-04 | 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-2021-36160 | 7 Apache, Broadcom, Debian and 4 more | 16 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 13 more | 2024-08-04 | 7.5 High |
| A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). | ||||
| CVE-2021-34798 | 9 Apache, Broadcom, Debian and 6 more | 21 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 18 more | 2024-08-04 | 7.5 High |
| Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier. | ||||
| CVE-2021-33193 | 5 Apache, Fedoraproject, Oracle and 2 more | 8 Http Server, Fedora, Secure Backup and 5 more | 2024-08-03 | 7.5 High |
| A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48. | ||||
| CVE-2021-32791 | 4 Apache, Fedoraproject, Openidc and 1 more | 4 Http Server, Fedora, Mod Auth Openidc and 1 more | 2024-08-03 | 5.9 Medium |
| mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In mod_auth_openidc before version 2.4.9, the AES GCM encryption in mod_auth_openidc uses a static IV and AAD. It is important to fix because this creates a static nonce and since aes-gcm is a stream cipher, this can lead to known cryptographic issues, since the same key is being reused. From 2.4.9 onwards this has been patched to use dynamic values through usage of cjose AES encryption routines. | ||||
| CVE-2021-32792 | 4 Apache, Fedoraproject, Openidc and 1 more | 4 Http Server, Fedora, Mod Auth Openidc and 1 more | 2024-08-03 | 3.1 Low |
| mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In mod_auth_openidc before version 2.4.9, there is an XSS vulnerability in when using `OIDCPreservePost On`. | ||||
| CVE-2021-32785 | 4 Apache, Debian, Netapp and 1 more | 4 Http Server, Debian Linux, Cloud Backup and 1 more | 2024-08-03 | 5.3 Medium |
| mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. When mod_auth_openidc versions prior to 2.4.9 are configured to use an unencrypted Redis cache (`OIDCCacheEncrypt off`, `OIDCSessionType server-cache`, `OIDCCacheType redis`), `mod_auth_openidc` wrongly performed argument interpolation before passing Redis requests to `hiredis`, which would perform it again and lead to an uncontrolled format string bug. Initial assessment shows that this bug does not appear to allow gaining arbitrary code execution, but can reliably provoke a denial of service by repeatedly crashing the Apache workers. This bug has been corrected in version 2.4.9 by performing argument interpolation only once, using the `hiredis` API. As a workaround, this vulnerability can be mitigated by setting `OIDCCacheEncrypt` to `on`, as cache keys are cryptographically hashed before use when this option is enabled. | ||||
| CVE-2021-32786 | 4 Apache, Fedoraproject, Openidc and 1 more | 4 Http Server, Fedora, Mod Auth Openidc and 1 more | 2024-08-03 | 4.7 Medium |
| mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In versions prior to 2.4.9, `oidc_validate_redirect_url()` does not parse URLs the same way as most browsers do. As a result, this function can be bypassed and leads to an Open Redirect vulnerability in the logout functionality. This bug has been fixed in version 2.4.9 by replacing any backslash of the URL to redirect with slashes to address a particular breaking change between the different specifications (RFC2396 / RFC3986 and WHATWG). As a workaround, this vulnerability can be mitigated by configuring `mod_auth_openidc` to only allow redirection whose destination matches a given regular expression. | ||||
| CVE-2021-31618 | 4 Apache, Debian, Fedoraproject and 1 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2024-08-03 | 7.5 High |
| Apache HTTP Server protocol handler for the HTTP/2 protocol checks received request headers against the size limitations as configured for the server and used for the HTTP/1 protocol as well. On violation of these restrictions and HTTP response is sent to the client with a status code indicating why the request was rejected. This rejection response was not fully initialised in the HTTP/2 protocol handler if the offending header was the very first one received or appeared in a a footer. This led to a NULL pointer dereference on initialised memory, crashing reliably the child process. Since such a triggering HTTP/2 request is easy to craft and submit, this can be exploited to DoS the server. This issue affected mod_http2 1.15.17 and Apache HTTP Server version 2.4.47 only. Apache HTTP Server 2.4.47 was never released. | ||||

| CVE-2022-37436 | 2 Apache, Redhat | 3 Http Server, Enterprise Linux, Jboss Core Services | 2024-08-03 | 5.3 Medium |
| Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated early, resulting in some headers being incorporated into the response body. If the later headers have any security purpose, they will not be interpreted by the client. | ||||
| CVE-2022-36760 | 2 Apache, Redhat | 3 Http Server, Enterprise Linux, Jboss Core Services | 2024-08-03 | 9.0 Critical |
| Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to.
