TITLE

Cisco NX-OS Software buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004596

DESCRIPTION

A vulnerability in the implementation of a specific CLI command for Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to cause a buffer overflow condition or perform command injection. This could allow the attacker to execute arbitrary commands with elevated privileges on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of arguments passed to a certain CLI command. An attacker could exploit this vulnerability by including malicious input as the argument of the affected CLI command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. An attacker would need valid administrator credentials to exploit these vulnerabilities. Cisco NX-OS Software is prone to multiple security vulnerabilities vulnerabilities. Failed exploits will result in denial-of-service condition. These issues are being tracked by Cisco Bug IDs CSCvh76129, CSCvh76132, CSCvj00497, CSCvj10162
