Apache 2.2.x < 2.2.28 Multiple Vulnerabilities

medium Nessus Plugin ID 77531
New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 6.7


The remote web server is affected by multiple vulnerabilities.


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 :

- A 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.

- A 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.


Upgrade to Apache version 2.2.29 or later.

Note that version 2.2.28 was never officially released.
