Apache 2.0.x < 2.0.48 Multiple Vulnerabilities (OF, Info Disc.)

critical Nessus Plugin ID 11853
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote web server is affected by multiple vulnerabilities.


The remote host appears to be running a version of Apache 2.0.x prior to 2.0.48. It is, therefore, affected by multiple vulnerabilities :

- The mod_rewrite and mod_alias modules fail to handle regular expressions containing more than 9 captures resulting in a buffer overflow.

- A vulnerability may occur in the mod_cgid module caused by the mishandling of CGI redirect paths. This could cause Apache to send the output of a CGI program to the wrong client.


Upgrade to Apache web server version 2.0.48 or later.
