Severe Cisco Vulnerability in Unified CM Allows Root Access via Hard-Coded Credentials

July 3, 2025
Vulnerability / Network Security

Cisco has issued patches to fix a critical security flaw in Unified Communications Manager (Unified CM) and Unified CM Session Management Edition (Unified CM SME). This vulnerability could enable an attacker to access susceptible devices with root privileges, achieving a CVSS score of 10.0 under the identifier CVE-2025-20309. In an advisory released on Wednesday, Cisco noted that “this vulnerability arises from the use of static user credentials for the root account, which are meant for development use only.” An attacker could exploit this flaw to log into an affected system and execute arbitrary commands as a root user. Hard-coded credentials often stem from testing or temporary fixes during development, but they should never be present in live environments.
