Apache 2.2.x < 2.2.28 Multiple Vulnerabilities

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote web server is affected by multiple vulnerabilities.

Description :

According to its banner, the version of Apache 2.2.x running on the
remote host is prior to 2.2.28. It is, therefore, affected by the
following vulnerabilities :

- An flaw exists within the 'mod_headers' module which
allows a remote attacker to inject arbitrary headers.
This is done by placing a header in the trailer portion
of data being sent using chunked transfer encoding.
(CVE-2013-5704)

- An flaw exists within the 'mod_deflate' module when
handling highly compressed bodies. Using a specially
crafted request, a remote attacker can exploit this to
cause a denial of service by exhausting memory and CPU
resources. (CVE-2014-0118)

- The 'mod_status' module contains a race condition that
can be triggered when handling the scoreboard. A remote
attacker can exploit this to cause a denial of service,
execute arbitrary code, or obtain sensitive credential
information. (CVE-2014-0226)

- The 'mod_cgid' module lacks a time out mechanism. Using
a specially crafted request, a remote attacker can use
this flaw to cause a denial of service by causing child
processes to linger indefinitely, eventually filling up
the scoreboard. (CVE-2014-0231)

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