Synopsis

Apache 2.4.x < 2.4.53 Multiple Vulnerabilities

Description

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.53. It is, therefore, affected by multiple vulnerabilities:

 - A carefully crafted request body can cause a read to a random memory area which could cause the process to crash. (CVE-2022-22719)

 - A HTTP Request Smuggling vulnerability exists due earlier fails to close inbound connection when errors are encountered discarding the request body. (CVE-2022-22720)

 - If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. (CVE-2022-22721)

 - An out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. (CVE-2022-23943)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache version 2.4.53 or later.
