TITLE

Cisco ASR 9000 Denial of service in the implementation of global settings for device software (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2015-004352

DESCRIPTION

The global-configuration implementation on Cisco ASR 9000 devices with software 5.1.3 and 5.3.0 improperly closes vty sessions after a commit/end operation, which allows local users to cause a denial of service (tmp/*config file creation, memory consumption, and device hang) via unspecified vectors, aka Bug ID CSCut93842. The Cisco ASR 9000 is Cisco's ultra-large capacity carrier-class edge router platform designed for the transformation of next-generation IP networks (IP NGNs). Cisco ASR 9000 is the ASR 9000 series multi-function router product of American Cisco (Cisco). There is a security vulnerability in the implementation of global-configuration in Cisco ASR 9000 devices using version 5.1.3 and 5.3.0 software. The vulnerability is caused by the program not properly closing the vty session after the commit/end operation
