ITM Server Missing Authentication for Agent Unregistration

ITM Server Missing Authentication for Agent Unregistration, CVE-2025-8558

Advisory ID: PFPT-SA-2025-0003

Insider Threat Management (ITM) Server versions prior to 7.17.2 contain an authentication bypass vulnerability that allows unauthenticated users on an adjacent network to perform agent unregistration when the number of registered agents exceeds the licensed limit.
