What is CVE-2011-3298?

The authentication bypass vulnerability in Cisco Adaptive Security Appliances (ASA) and the Firewall Services Module (FWSM) allows remote attackers to gain unauthorized access by exploiting a crafted TACACS+ reply. This flaw affects multiple versions across the ASA 5500 series and the ASA Services module in Cisco Catalyst 6500 series devices. The affected systems fail to adequately validate the responses from the TACACS+ protocol, leading to potential unauthorized control over the network devices. To mitigate risks, affected users should upgrade to the recommended software versions listed in Cisco's security advisories.
