Name of the Vulnerable Software and Affected Versions Check Point Harmony Browse and SandBlast Agent for Browsers versions prior to 90.08.7405

Description The issue arises because the MS Installer allows regular users to repair their installation. An attacker can exploit this by running an installer, starting the installation repair, and placing a specially crafted binary in the repair folder, which then runs with admin privileges.

Recommendations For versions prior to 90.08.7405, update to version 90.08.7405 or later to resolve the issue. As a temporary workaround, consider restricting access to the installation repair feature to minimize the risk of exploitation.
