Cisco Small Business Switches Privileged Access Vulnerability

CVSS 9.8 CRITICALEPSS 49.7%CWE-798
In short

A Cisco Small Business Switch can be accessed remotely without a password due to a hidden privileged account that is automatically enabled. An attacker can log in with full administrator rights and take complete control of the network device.

Technical detail

An unauthenticated remote attacker can bypass authentication by exploiting a privileged account that is enabled under specific circumstances without administrator notification (CWE-798: Use of Hardcoded Credentials). The attack vector is network-based with no authentication required, allowing arbitrary command execution with full administrative privileges on affected Cisco Small Business Switches.
