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: 6.6

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 GIT 1.5.6 or later.
