Title: Cisco IOS Extended Access List Failure Vulnerability
Severity: MODERATE
Description:
IOS is the firmware used by many Cisco network devices.
In some versions of IOS 12.x (verified on 12.1(4) and reportedly other versions), certain rules in extended access control lists will not be enforced. This may allow attackers to access vulnerable network services thought to be protected by the access control lists. The reason for this behaviour is not yet known.
Affected Products:
- Cisco IOS 12.1(4)
