| CVE-2021-34798 | 0.01 | — | 0.65 | Sep 16, 2021 | Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier. | |||
| CVE-2021-31618 | 0.01 | — | 0.51 | Jun 15, 2021 | 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… | |||
| CVE-2020-35452 | 0.01 | — | 0.53 | Jun 10, 2021 | 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… | |||
| CVE-2020-13950 | 0.01 | — | 0.49 | Jun 10, 2021 | 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-2019-17567 | 0.01 | — | 0.60 | Jun 10, 2021 | 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… | |||
| CVE-2020-11985 | 0.01 | — | 0.06 | Aug 7, 2020 | 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… | |||
| CVE-2019-0196 | 0.01 | — | 0.19 | Jun 11, 2019 | A vulnerability was found in Apache HTTP Server 2.4.17 to 2.4.38. Using fuzzed network input, the http/2 request handling could be made to access freed memory in string comparison when determining the method of a request and thus process the request incorrectly. | |||
| CVE-2018-17189 | 0.01 | — | 0.19 | Jan 30, 2019 | In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections. | |||
| CVE-2018-17199 | 0.01 | — | 0.20 | Jan 30, 2019 | In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded. | |||

| CVE-2013-4352 | 0.01 | — | 0.12 | Jul 20, 2014 | The cache_invalidate function in modules/cache/cache_storage.c in the mod_cache module in the Apache HTTP Server 2.4.6, when a caching forward proxy is enabled, allows remote HTTP servers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that… | |||
| CVE-2013-2249 | 0.01 | — | 0.14 | Jul 23, 2013 | mod_session_dbd.c in the mod_session_dbd module in the Apache HTTP Server before 2.4.5 proceeds with save operations for a session without considering the dirty flag and the requirement for a new session ID, which has unspecified impact and remote attack vectors. | |||
| CVE-2012-4557 | 0.01 | — | 0.17 | Nov 30, 2012 | The mod_proxy_ajp module in the Apache HTTP Server 2.2.12 through 2.2.21 places a worker node into an error state upon detection of a long request-processing time, which allows remote attackers to cause a denial of service (worker consumption) via an expensive request. | |||
