Technical details
An SQL injection vulnerability (CWE-89) exists in the UserChoice flow of the Check Point UserCheck Web Portal. When the Data Loss Prevention (DLP) blade is active, the portal fails to properly sanitize input on the 'UserCheck Ask' page. A network-based attacker with low privileges can exploit this to manipulate the Security Gateway's stored incident database. Successful exploitation can result in the deletion of incident entries, incorrect processing of pending security approvals, or resource exhaustion through repeated abuse. The vulnerability is reachable via the network, though exposure is limited if the portal is not accessible from untrusted networks.
