Apache >= 2.4.30 < 2.4.49 mod_proxy_uwsgi

high Nessus Plugin ID 153586

Language:

Synopsis

The remote web server is affected by a vulnerability.

Description

The version of Apache httpd installed on the remote host greater than 2.4.30 and is prior to 2.4.49. It is, therefore, affected by a vulnerability as referenced in the 2.4.49 changelog. A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS).

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache version 2.4.49 or later.
