SquidClamav clwarn.cgi url Parameter XSS

medium Nessus Plugin ID 62030

Synopsis

The remote web server hosts a CGI script that is affected by a cross-site scripting vulnerability.

Description

The version of SquidClamav installed on the remote host is affected by a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input to the 'url' parameter of the 'clwarn.cgi' script. An attacker may leverage this issue to execute arbitrary script in the browser of an unsuspecting user to be executed within the security context of the affected site.

Note that the application is also reportedly affected by cross-site scripting vulnerabilities with the 'source', 'virus' and 'user' parameters of the 'clwarn.cgi' script but Nessus has not tested the additional parameters.

Solution

Update to version 5.8 / 6.7 or later.
