CVE-2020-3572

TITLE

Cisco Adaptive Security Appliance Software and Cisco Firepower Threat Defense Software exhaustion vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2020-009716

DESCRIPTION

A vulnerability in the SSL/TLS session handler of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a memory leak when closing SSL/TLS connections in a specific state. An attacker could exploit this vulnerability by establishing several SSL/TLS sessions and ensuring they are closed under certain conditions. A successful exploit could allow the attacker to exhaust memory resources in the affected device, which would prevent it from processing new SSL/TLS connections, resulting in a DoS. Manual intervention is required to recover an affected device. The platform provides features such as highly secure access to data and network resources
