| CVE-2021-36160 | 7 Apache, Broadcom, Debian and 4 more | 16 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 13 more | 2024-11-21 | 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 | 2024-11-21 | 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 | 2024-11-21 | 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-2021-32792 | 4 Apache, Fedoraproject, Openidc and 1 more | 4 Http Server, Fedora, Mod Auth Openidc and 1 more | 2024-11-21 | 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-2021-32791 | 4 Apache, Fedoraproject, Openidc and 1 more | 4 Http Server, Fedora, Mod Auth Openidc and 1 more | 2024-11-21 | 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-2021-32786 | 4 Apache, Fedoraproject, Openidc and 1 more | 4 Http Server, Fedora, Mod Auth Openidc and 1 more | 2024-11-21 | 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-2021-32785 | 4 Apache, Debian, Netapp and 1 more | 4 Http Server, Debian Linux, Cloud Backup and 1 more | 2024-11-21 | 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-2021-31618 | 4 Apache, Debian, Fedoraproject and 1 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2024-11-21 | 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-2021-30641 | 5 Apache, Debian, Fedoraproject and 2 more | 8 Http Server, Debian Linux, Fedora and 5 more | 2024-11-21 | 5.3 Medium |
| Apache HTTP Server versions 2.4.39 to 2.4.46 Unexpected matching behavior with 'MergeSlashes OFF' | ||||
| CVE-2021-26691 | 6 Apache, Debian, Fedoraproject and 3 more | 10 Http Server, Debian Linux, Fedora and 7 more | 2024-11-21 | 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-2021-26690 | 5 Apache, Debian, Fedoraproject and 2 more | 8 Http Server, Debian Linux, Fedora and 5 more | 2024-11-21 | 7.5 High |
| 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-2020-9490 | 7 Apache, Canonical, Debian and 4 more | 28 Http Server, Ubuntu Linux, Debian Linux and 25 more | 2024-11-21 | 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 | 5 Apache, Debian, Fedoraproject and 2 more | 8 Http Server, Debian Linux, Fedora and 5 more | 2024-11-21 | 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-2020-1934 | 7 Apache, Canonical, Debian and 4 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2024-11-21 | 5.3 Medium |
| In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server. | ||||
| CVE-2020-1927 | 9 Apache, Broadcom, Canonical and 6 more | 17 Http Server, Brocade Fabric Operating System, Ubuntu Linux and 14 more | 2024-11-21 | 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. | ||||
| CVE-2020-13950 | 5 Apache, Debian, Fedoraproject and 2 more | 8 Http Server, Debian Linux, Fedora and 5 more | 2024-11-21 | 7.5 High |
| 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-2020-13938 | 4 Apache, Mcafee, Microsoft and 1 more | 4 Http Server, Epolicy Orchestrator, Windows and 1 more | 2024-11-21 | 5.5 Medium |
| Apache HTTP Server versions 2.4.0 to 2.4.46 Unprivileged local users can stop httpd on Windows | ||||
| CVE-2020-11993 | 8 Apache, Canonical, Debian and 5 more | 16 Http Server, Ubuntu Linux, Debian Linux and 13 more | 2024-11-21 | 7.5 High |
| Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. | ||||
| CVE-2020-11985 | 2 Apache, Redhat | 3 Http Server, Enterprise Linux, Rhel Software Collections | 2024-11-21 | 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. | ||||
| CVE-2020-11984 | 8 Apache, Canonical, Debian and 5 more | 16 Http Server, Ubuntu Linux, Debian Linux and 13 more | 2024-11-21 | 9.8 Critical |
