High

Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions: Cisco IOS versions 12.2T through 12.4

Description: The issue allows remote attackers to bypass Authentication, Authorization, and Accounting (AAA) RADIUS authentication. This can occur when the fallback method is set to none, and a long username is provided.

Recommendations: For Cisco IOS versions 12.2T through 12.4, consider setting the fallback method to a value other than none to prevent bypassing AAA RADIUS authentication. As a temporary workaround, restrict access to the RADIUS authentication mechanism until a patch is available.
