Last modified
CVE-2015-0607 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.97% chance of exploitation in the next 30 days.
