Apache 2.4.x < 2.4.2 'LD_LIBRARY_PATH' Insecure Library Loading

high Nessus Plugin ID 58795

Synopsis

The remote web server is affected by an insecure library loading issue.

Description

According to its banner, the version of Apache 2.4.x running on the remote host is prior to 2.4.2. It is, therefore, potentially affected by an insecure library loading issue.

The utility 'apachectl' can receive a zero-length directory name in the LD_LIBRARY_PATH via the 'envvars' file. A local attacker with access to that utility could exploit this to load a malicious Dynamic Shared Object (DSO), leading to arbitrary code execution.

Note that Nessus did not actually test for this flaw, but instead has relied on the version in the server's banner.

Solution

Upgrade to Apache version 2.4.2 or later.
