Title: Active Classifieds Arbitrary Code Execution Vulnerability
Severity: CRITICAL
Description:
Active Classifieds is a CGI package that provides an online classified advertisement listing and management system.
An origin validation error exists in the Free Edition of Active Classifieds that may allow remote users to cause arbitrary commands to be executed on a host running the software.
The problem occurs because some of the subroutines used in the 'admin.cgi' script allow administrative commands to be performed without checking for authentication. This makes it possible for a remote user to alter configuration files used by the software.
The contents of the configuration files are loaded and executed by the Perl interpreter when a script from the package is run. As a result, it is possible for an attacker to cause arbitrary commands to be executed on the host by inserting malicious Perl code into configuration files.
It is currently unclear as to whether commercial versions of Active Classifieds are also vulnerable.
