GIT gitweb git_search Shell Metacharacter Arbitrary Command Execution

high Nessus Plugin ID 53336
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.

Synopsis

The remote web server contains a CGI script that can be abused to execute arbitrary commands.

Description

The version of gitweb, a web-enabled interface to the open source distributed version control system Git, hosted on the remote web server fails to sanitize user-supplied input to the 'gitweb.cgi' script of shell metacharacters before passing it to a shell.

An unauthenticated, remote attacker can leverage this issue to execute arbitrary commands subject to the privileges under which the web server operates.

Solution

Upgrade to version 1.5.6 or later.
