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.

Security readout for executives and security teams

Cisco Policy Suite can incorrectly accept a subscriber login through RADIUS when the attacker knows a valid username but does not provide a valid password. This matters where CPS domains use RADIUS authentication. The source bundle does not show confirmed active exploitation. Exposure is limited to Cisco Policy Suite deployments with domains configured for RADIUS authentication, especially releases before 13.1.0 Hotfix Patch 1. CPS 14.0.0 also includes vulnerable code, but the provided source says RADIUS is not officially supported in 14.0.0 and later. Prioritize remediation where Cisco Policy Suite protects subscriber access and RADIUS authentication is enabled. The issue can bypass passwords with only a valid username, but the supplied evidence does not prove active exploitation. Mitigation focus: Upgrade affected CPS deployments to 13.1.0 Hotfix Patch 1 or later per Cisco guidance.; Review Cisco advisory and Bug ID CSCvg40124 for vendor-supported remediation details.; Identify and prioritize CPS domains using RADIUS authentication..

Improper Authentication

Improper Authentication represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
