radsecproxy before 1.6.1 does not properly verify certificates when there are configuration blocks with CA settings that are unrelated to the block being used for verifying the certificate chain, which might allow remote attackers to bypass intended access restrictions and spoof clients.

Security readout for executives and security teams

This flaw affects radsecproxy before 1.6.1. In some configurations, the service could validate a client certificate using CA settings from the wrong configuration block. That could let a remote party appear as an allowed client and bypass intended access restrictions. Exposure is likely limited to organizations running radsecproxy before 1.6.1, especially where TLS client certificates and multiple CA-related configuration blocks are used. The provided data does not identify broader products, CPEs, or exact affected deployment patterns. Prioritize remediation where radsecproxy protects RADIUS federation, roaming, or partner access. Business risk is unauthorized client impersonation, but urgency is moderated by incomplete severity data and no cited active exploitation. Mitigation focus: Upgrade radsecproxy to version 1.6.1 or later.; Check Debian or other vendor advisories for packaged fixes.; Review radsecproxy TLS client-certificate CA configuration for unintended trust relationships..
