| 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. | ||||

| 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 |
| Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE | ||||
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 28 Http Server, Traffic Server, Mac Os X and 25 more | 2024-11-21 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. | ||||
| CVE-2019-17567 | 4 Apache, Fedoraproject, Oracle and 1 more | 6 Http Server, Fedora, Enterprise Manager Ops Center and 3 more | 2024-11-21 | 5.3 Medium |
| Apache HTTP Server versions 2.4.6 to 2.4.46 mod_proxy_wstunnel configured on an URL that is not necessarily Upgraded by the origin server was tunneling the whole connection regardless, thus allowing for subsequent requests on the same connection to pass through with no HTTP validation, authentication or authorization possibly configured. | ||||
| CVE-2019-10098 | 2 Apache, Redhat | 4 Http Server, Enterprise Linux, Jboss Core Services and 1 more | 2024-11-21 | 6.1 Medium |
| In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the request URL. | ||||
| CVE-2019-10097 | 3 Apache, Oracle, Redhat | 11 Http Server, Communications Element Manager, Communications Session Report Manager and 8 more | 2024-11-21 | 7.2 High |
| In Apache HTTP Server 2.4.32-2.4.39, when mod_remoteip was configured to use a trusted intermediary proxy server using the "PROXY" protocol, a specially crafted PROXY header could trigger a stack buffer overflow or NULL pointer deference. This vulnerability could only be triggered by a trusted proxy and not by untrusted HTTP clients. | ||||
| CVE-2019-10092 | 8 Apache, Canonical, Debian and 5 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2024-11-21 | 6.1 Medium |
| In Apache HTTP Server 2.4.0-2.4.39, a limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malformed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed. | ||||
| CVE-2019-10082 | 3 Apache, Oracle, Redhat | 8 Http Server, Communications Element Manager, Enterprise Manager Ops Center and 5 more | 2024-11-21 | 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-2019-10081 | 3 Apache, Debian, Redhat | 4 Http Server, Debian Linux, Enterprise Linux and 1 more | 2024-11-21 | N/A |
| HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client. | ||||
