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 the lack of protection for internal data in the McAfee Web Gateway. It allows a remote attacker to disclose protected information using a specially crafted webpage. This can be achieved by creating a complex webpage that triggers the Web Gateway to block a user from accessing an iframe, thereby allowing the attacker to obtain sensitive data.

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 iframes or implementing additional security measures to minimize the risk of exploitation.
