[GLSA]

Gentoo Linux Security Advisory

Title: AWStats: Remote code execution (GLSA 200501-36)
Severity: high
Exploitable: remote
Date: January 25, 2005
Updated: May 28, 2009
Bug(s): #77963, #81775
ID: 200501-36

Synopsis

AWStats fails to validate certain input, which could lead to the remote execution of arbitrary code or to the leak of information.

Background

AWStats is an advanced log file analyzer and statistics generator.

Affected Packages

Package: www-misc/awstats
Vulnerable: < 6.3-r2
Unaffected: >= 6.3-r2
Architectures: All supported architectures


Description

When 'awstats.pl' is run as a CGI script, it fails to validate specific inputs which are used in a Perl open() function call. Furthermore, a user could read log file content even when plugin rawlog was not enabled.

Impact

A remote attacker could supply AWStats malicious input, potentially allowing the execution of arbitrary code with the rights of the web server. He could also access raw log contents.

Workaround

Making sure that AWStats does not run as a CGI script will avoid the issue, but we recommend that users upgrade to the latest version, which fixes these bugs.

Resolution

All AWStats users should upgrade to the latest version:
