methods or that are not configured with a fallback method to none are
not affected. Only the systems that are running certain versions of
Cisco IOS are affected. Not all configurations using RADIUS and none
are vulnerable to this issue. Some configurations using RADIUS, none
and an additional method are not affected. Cisco has made free
software available to address this vulnerability. There are
workarounds available to mitigate the effects of the vulnerability.
The vulnerabilities are documented as the following Cisco Bug ID:
CSCee45312 -- Radius authentication bypass when configured with a none
