CUPS < 1.7.2 is_path_absolute Function XSS

medium Nessus Plugin ID 73734

Synopsis

The remote print service is affected by a cross-site scripting vulnerability.

Description

According to its banner, the version of CUPS installed on the remote host is prior to version 1.7.2. It is, therefore, affected by a cross-site scripting vulnerability.

A flaw exists with the is_path_absolute function within the scheduler/client.cscript. This could allow a context-dependent attacker, with a specially crafted request, to execute arbitrary script code within the browser and server trust relationship.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to CUPS version 1.7.2 or later, or apply the vendor patch.
