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 11.1 through 11.3

Description: A security issue allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled input interface to an output interface with a logical subinterface.

Recommendations: For Cisco IOS versions 11.1 through 11.3, consider disabling distributed fast switching (DFS) as a temporary workaround until a patch is available. Restrict access to interfaces with logical subinterfaces to minimize the risk of exploitation.
