Apache 2.2.x < 2.2.9 Multiple Vulnerabilities (DoS, XSS)

Medium Nessus Plugin ID 33477

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's different from CVSS.

VPR Score: 3.6


The remote web server may be affected by several issues.


According to its banner, the version of Apache 2.2.x running on the remote host is prior to 2.2.9. It is, therefore, affected by multiple vulnerabilities :

- Improper handling of excessive forwarded interim responses may cause denial of service conditions in mod_proxy_http. (CVE-2008-2364)

- A cross-site request forgery vulnerability in the balancer-manager interface of mod_proxy_balancer.

Note that the remote web server may not actually be affected by these vulnerabilities. Nessus did not try to determine whether the affected modules are in use or to check for the issues themselves.


Upgrade to Apache version 2.2.9 or later. Alternatively, ensure that the affected modules are not in use.
