Apache >= 2.4.30 < 2.4.49 mod_proxy_uwsgi

high Nessus Plugin ID 153586
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
