Critical Cisco Unity Connection flaw gives attackers root privileges. Patch now! (CVE-2024-20272)

Cisco has fixed a critical vulnerability in Cisco Unity Connection that could allow an unauthenticated attacker to upload arbitrary files and gain root privilege on the affected system.

Cisco Unity Connection is a unified messaging and voicemail solution for email inbox, web browser, Cisco Jabber, Cisco Unified IP Phone, smartphone, and tablet.

CVE-2024-20272 is an unauthenticated arbitrary file upload vulnerability in the web-based management interface of Cisco Unity Connection that could be exploited by a remote, unauthenticated threat actor to upload arbitrary files to a targeted system, execute commands on the underlying operating system and gain root privileges.

CVE-2024-20272, reported by software development consultant Maxim Suslov, affects Cisco Unity Connection software releases 12.5 and 14 – but not version 15.

Vulnerabilities in Cisco solutions are often leveraged by attackers.

Last September, Cisco “Hotfixed” a vulnerability in Cisco Adaptive Security Appliance and Cisco Firepower Threat Defense firewalls that was being exploited in the wild.
