A vulnerability in the RADIUS authentication module of Cisco Policy Suite could allow an unauthenticated, remote attacker to determine whether a subscriber username is valid. The vulnerability occurs because the Cisco Policy Suite RADIUS server component returns different authentication failure messages based on the validity of usernames. An attacker could use these messages to determine whether a valid subscriber username has been identified. The attacker could use this information in subsequent attacks against the system. Cisco Bug IDs: CSCvg47830.

Security readout for executives and security teams

Cisco Policy Suite could reveal whether a subscriber username exists because its RADIUS component returned different authentication failure messages. Alone, this is not system compromise, but it can help attackers build valid-user lists for password spraying, phishing, or other follow-on attacks. Organizations using Cisco Policy Suite with its RADIUS server component reachable by untrusted or broad networks are the primary concern. The bundle does not identify specific affected versions beyond Cisco Policy Suite. Treat this as a moderate exposure-reduction item. It is not described as direct takeover, but it can lower the effort for later credential attacks against subscriber accounts. Mitigation focus: Review Cisco advisory cisco-sa-20180207-cps1 for affected and fixed release guidance.; Check Cisco Bug ID CSCvg47830 against installed Cisco Policy Suite deployments.; Restrict RADIUS access to trusted clients and management networks where operationally possible..

Exposure of Sensitive Information to an Unauthorized Actor

Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
