Apache mod_fcgid Module fcgid_header_bucket_read() Function Remote Stack Buffer Overflow

high Nessus Plugin ID 54607

Language:

Synopsis

The remote web server is at risk of a buffer overflow attack.

Description

According to its self-reported banner, the Apache web server listening on this port includes a version of the mod_fcgid module earlier than 2.3.6. As such, it has a stack-based buffer overflow vulnerability because of an error in the pointer arithmetic used in the 'fcgid_header_bucket_read()' function.

An unauthenticated, remote attacker can leverage this with a specially crafted request to overwrite data on the stack, leading to an application crash or possibly even arbitrary code execution subject to the privileges under which the web server operates.

Solution

Update to version 2.3.6 or later.
