Senserva AI Opinion for CVE-2024-41713

This is the unauthenticated half of the Mitel MiCollab exploit chain: a path traversal rated Critical at CVSS 9.1 with a 98% EPSS score that grants access without credentials, then pairs with CVE-2024-55550 to read arbitrary files off the server. Ransomware use is confirmed, and it has been in the KEV catalog since 2025-01-07. MiCollab servers sit at the center of enterprise voice and messaging, often internet-reachable for remote workers.

Do this: Update MiCollab immediately and remove direct internet exposure of the server if remote access does not strictly require it.
