Privilege Escalation Flaw in Cisco AsyncOS for Secure Email and Web Solutions

CVE-2025-20185

Summary

A vulnerability exists in the remote access functionality of Cisco AsyncOS Software used in Cisco Secure Email and Web appliances, allowing an authenticated local attacker to gain root privileges. This flaw arises from an architectural weakness in the password generation algorithm specific to remote access. By exploiting this vulnerability, an attacker with valid administrative credentials can generate a temporary service account password, leading to the ability to execute arbitrary commands as the root user and access the underlying operating system, posing significant security risks to affected systems.
