Technical description

The web interface in CUPS before 1.4.2, as used on Apple Mac OS X before 10.6.2 and other platforms, does not properly handle (1) HTTP headers and (2) HTML templates, which allows remote attackers to conduct cross-site scripting (XSS) attacks and HTTP response splitting attacks via vectors related to (a) the product's web interface, (b) the configuration of the print system, and (c) the titles of printed jobs, as demonstrated by an XSS attack that uses the kerberos parameter to the admin program, and leverages attribute injection and HTTP Parameter Pollution (HPP) issues.

Remediation

Check the references section for vendor advisories and patches from apple. Update mac_os_x to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
