TITLE

Cisco Adaptive Security Appliance Software and Cisco Firepower Threat Defense Software Resource exhaustion vulnerability in

Trust: 0.8

sources: JVNDB: JVNDB-2021-014298

DESCRIPTION

A vulnerability in SSL/TLS message handler for 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. This vulnerability exists because incoming SSL/TLS packets are not properly processed. An attacker could exploit this vulnerability by sending a crafted SSL/TLS packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition

Trust: 1.8
