In Less Than 24 Hours, Attackers Weaponize Cisco CUCM Flaw

By Jai Vijayan

AI Summary

A newly disclosed Cisco Unified Communications Manager (CUCM) flaw enabling SSRF and privilege escalation to root was weaponized by attackers within 24 hours of public disclosure, affecting both Unified CM and Unified CM SME deployments. The rapid exploitation window gives defenders essentially no patch buffer and illustrates the continued targeting of Cisco unified communications infrastructure. Administrators should prioritize emergency patching and review CUCM exposure to the internet immediately.
