⚡ Weekly Recap: Fortinet Exploits, Red Line Clipjack, NTLM Crack, Copilot Attack & More

Summary: A critical Fortinet FortiSIEM flaw tracked as CVE-2025-64155, with a CVSS score of 9.4, is under active exploitation in the wild and allows an unauthenticated attacker to execute unauthorized code or commands via crafted TCP requests. Horizon3.ai's analysis describes it as an unauthenticated argument injection leading to arbitrary file write and remote code execution as the admin user, plus a file overwrite privilege escalation to root, both in the phMonitor service that runs with elevated privileges.

What you should know: Exploitation of phMonitor grants full control of the appliance, and the recap's wider flaw list spans Cisco, Palo Alto Networks, Microsoft, SAP, ServiceNow, Apache Struts 2 and Node.js - so a single missed update on one internet-facing service is the opening an attacker needs.
