CVE-2020-3555

TITLE

Cisco Adaptive Security Appliance and Cisco Firepower Threat Defense Improper resource shutdown and release vulnerabilities in software

Trust: 0.8

sources: JVNDB: JVNDB-2020-012600

DESCRIPTION

A vulnerability in the SIP inspection process of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a crash and reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a watchdog timeout and crash during the cleanup of threads that are associated with a SIP connection that is being deleted from the connection list. An attacker could exploit this vulnerability by sending a high rate of crafted SIP traffic through an affected device. A successful exploit could allow the attacker to cause a watchdog timeout and crash, resulting in a crash and reload of the affected device. Cisco Adaptive Security Appliances Software is a firewall and network security platform. The platform provides features such as highly secure access to data and network resources
