CVE-2010-2814: Unspecified vulnerability in the Transport Layer Security (TLS) implementation on Cisco Adaptive Security A...

Security readout for executives and security teams

This vulnerability can let a remote attacker crash and reload affected Cisco ASA 5500 or PIX 500 security appliances by sending crafted TLS packets. The main business risk is outage of firewall or VPN services, not confirmed data theft or code execution. Exposure is most likely where vulnerable ASA or PIX appliances still handle TLS from untrusted networks, including VPN, management, or other TLS-enabled services. Modern environments should verify because these product lines and versions are old but may persist in legacy networks. Prioritize remediation for internet-facing VPN or perimeter devices because a reload can disrupt access and traffic flow. Lower priority may be reasonable for retired, isolated, or already-upgraded appliances. Mitigation focus: Upgrade affected ASA software to the fixed versions listed by Cisco or later.; Review Cisco advisory CSCtf37506 for appliance-specific guidance.; Restrict TLS-exposed services to trusted networks where operationally possible..
