TITLE

Cisco Firepower Threat Defense Software resource management vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-011567

DESCRIPTION

A vulnerability in the FTP inspection engine of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software fails to release spinlocks when a device is running low on system memory, if the software is configured to apply FTP inspection and an access control rule to transit traffic, and the access control rule is associated with an FTP file policy. An attacker could exploit this vulnerability by sending a high rate of transit traffic through an affected device to cause a low-memory condition on the device. A successful exploit could allow the attacker to cause a software panic on the affected device, which could cause the device to reload and result in a temporary DoS condition. This issue is being tracked by Cisco Bug ID CSCvh77456. Cisco 3000 Series Industrial Security Appliances and so on are different series of security equipment of Cisco (Cisco). The following products are affected: Cisco 3000 Series Industrial Security Appliances (ISAs); ASA 5500-X Series Next-Generation Firewalls; Firepower 2100 Series Security Appliances; Firepower 4100 Series Security Appliances;
