Synopsis

Apache 2.4.x < 2.4.52 Multiple Vulnerabilities

Description

The version of Apache httpd installed on the remote host is prior to 2.4.52. It is, therefore, affected by multiple vulnerabilities as referenced in the 2.4.52 advisory.

 - 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-2021-44224)

 - A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. (CVE-2021-44790)

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 2.4.52 or later.
