| A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). | |||||
| CVE-2021-41524 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2023-11-07 | 5.0 MEDIUM | 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. | |||||
| CVE-2021-34798 | 8 Apache, Broadcom, Debian and 5 more | 18 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 15 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |

| CVE-2021-32786 | 3 Apache, Fedoraproject, Openidc | 3 Http Server, Fedora, Mod Auth Openidc | 2023-11-07 | 5.8 MEDIUM | 6.1 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-2021-32791 | 3 Apache, Fedoraproject, Openidc | 3 Http Server, Fedora, Mod Auth Openidc | 2023-11-07 | 4.3 MEDIUM | 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 | 3 Apache, Fedoraproject, Openidc | 3 Http Server, Fedora, Mod Auth Openidc | 2023-11-07 | 4.3 MEDIUM | 6.1 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, there is an XSS vulnerability in when using `OIDCPreservePost On`. | |||||
| CVE-2021-30641 | 4 Apache, Debian, Fedoraproject and 1 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| Apache HTTP Server versions 2.4.39 to 2.4.46 Unexpected matching behavior with 'MergeSlashes OFF' | |||||

| Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can cause a NULL pointer dereference and crash, leading to a possible Denial Of Service | |||||
| CVE-2021-26691 | 5 Apache, Debian, Fedoraproject and 2 more | 8 Http Server, Debian Linux, Fedora and 5 more | 2023-11-07 | 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-2020-9490 | 7 Apache, Canonical, Debian and 4 more | 25 Http Server, Ubuntu Linux, Debian Linux and 22 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. | |||||
| CVE-2020-35452 | 4 Apache, Debian, Fedoraproject and 1 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2023-11-07 | 6.8 MEDIUM | 7.3 HIGH |
| Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow | |||||
| CVE-2020-1927 | 8 Apache, Broadcom, Canonical and 5 more | 14 Http Server, Brocade Fabric Operating System, Ubuntu Linux and 11 more | 2023-11-07 | 5.8 MEDIUM | 6.1 MEDIUM |
| In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL. | |||||

| Apache HTTP Server versions 2.4.41 to 2.4.46 mod_proxy_http can be made to crash (NULL pointer dereference) with specially crafted requests using both Content-Length and Transfer-Encoding headers, leading to a Denial of Service | |||||
| CVE-2020-11985 | 1 Apache | 1 Http Server | 2023-11-07 | 4.3 MEDIUM | 5.3 MEDIUM |
| IP address spoofing when proxying using mod_remoteip and mod_rewrite For configurations using proxying with mod_remoteip and certain mod_rewrite rules, an attacker could spoof their IP address for logging and PHP scripts. Note this issue was fixed in Apache HTTP Server 2.4.24 but was retrospectively allocated a low severity CVE in 2020. | |||||
