Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200501-36 (AWStats: Remote code execution)

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.

Solution

All AWStats users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=www-misc/awstats-6.3-r2' Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB, GitHub)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the GLSA-200501-36 : AWStats: Remote code execution vulnerability:

Metasploit: exploit/unix/webapp/awstats_configdir_exec
[AWStats configdir Remote Command Execution]
Exploit-DB: exploits/cgi/webapps/9912.rb
[EDB-9912: AWStats 6.2 < 6.1 - configdir Command Injection (Metasploit)]
Exploit-DB: exploits/cgi/webapps/16905.rb
