Vulnerability Information

Severity: High
Vulnerability Published: 2005-01-01
Patch Published: N/A
CVE [?]: CVE-2005-0116
CPE [?]: cpe:/a:laurent_destailleur:awstats

Synopsis

The remote web server contains a CGI script that allows execution of arbitrary commands.

Description

The remote host is running AWStats, a free logfile analysis tool for analyzing ftp, mail, web, ... traffic.

The remote version of this software fails to sanitize user-supplied input to the 'configdir' parameter of the 'awstats.pl' script. An attacker may exploit this condition to execute commands remotely or disclose contents of files, subject to the privileges under which the web server operates.

Solution

Upgrade to AWStats version 6.3 or later.
