Name of the Vulnerable Software and Affected Versions McAfee Web Gateway versions 7.8.2.x prior to 7.8.2.12

Description The issue is related to insufficient input validation in the Administrator web console of McAfee Web Gateway. It allows a remote attacker to conduct a clickjacking attack using a specially crafted web page that contains an iframe, as the web page does not send an X-Frame-Options HTTP header.

Recommendations For McAfee Web Gateway versions 7.8.2.x prior to 7.8.2.12, update to version 7.8.2.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the Administrator web console to minimize the risk of exploitation.
