Description

A vulnerability in a debug function for Cisco RCM for Cisco StarOS Software could allow an unauthenticated, remote attacker to perform debug actions that could result in the disclosure of confidential information that should be restricted. This vulnerability exists because of a debug service that incorrectly listens to and accepts incoming connections. An attacker could exploit this vulnerability by connecting to the debug port and executing debug commands. A successful exploit could allow the attacker to view sensitive debugging information.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
