Source headline: Cisco finally confirms attackers exploiting Unified CM flaw
Intelligence Summary
Cisco says attackers are actively exploiting a vulnerability in Unified Communications Manager (Unified CM). The flaw was patched in early June by Cisco. Public details indicate the issue affects deployed Unified CM systems. This matters because exploitation suggests real-world risk beyond proof-of-concept testing. Organizations using Unified CM should verify they are fully updated with the patched releases and review related security guidance.
