CVE-2015-0607: The Authentication Proxy feature in Cisco IOS does not properly handle invalid AAA return codes from RADIUS...

The Authentication Proxy feature in Cisco IOS does not properly handle invalid AAA return codes from RADIUS and TACACS+ servers, which allows remote attackers to bypass authentication in opportunistic circumstances via a connection attempt that triggers an invalid code, as demonstrated by a connection attempt with a blank password, aka Bug IDs CSCuo09400 and CSCun16016.

Security readout for executives and security teams

CVE-2015-0607 is an authentication-bypass issue in Cisco IOS Authentication Proxy. Under certain AAA error conditions from RADIUS or TACACS+ servers, a remote connection attempt could be allowed without proper authentication. The bundle does not identify affected IOS versions or fixed releases. Exposure is most likely where Cisco IOS Authentication Proxy is enabled and depends on RADIUS or TACACS+ AAA. The supplied source data does not prove exposure for all Cisco IOS deployments and lists affected products and versions as unavailable. Prioritize review for environments using Cisco IOS Authentication Proxy on access-control paths. The issue can undermine authentication, but urgency depends on feature use, AAA architecture, and Cisco's affected-release guidance. Mitigation focus: Review Cisco's advisory for affected releases and official remediation.; Check Cisco bug IDs CSCuo09400 and CSCun16016 for applicability.; Identify devices using IOS Authentication Proxy with RADIUS or TACACS+ AAA..
