Description

A vulnerability in the RADIUS authentication module of Cisco Policy Suite could allow an unauthenticated, remote attacker to be authorized as a subscriber without providing a valid password; however, the attacker must provide a valid username. The vulnerability is due to incorrect RADIUS user credential validation. An attacker could exploit this vulnerability by attempting to access a Cisco Policy Suite domain configured with RADIUS authentication. An exploit could allow the attacker to be authorized as a subscriber without providing a valid password. This vulnerability affects the Cisco Policy Suite application running a release prior to 13.1.0 with Hotfix Patch 1 when RADIUS authentication is configured for a domain. Cisco Policy Suite Release 14.0.0 is also affected, as it includes vulnerable code, but RADIUS authentication is not officially supported in Cisco Policy Suite Releases 14.0.0 and later. Cisco Bug IDs: CSCvg40124.
