TITLE

Cisco NX-OS In software OS Command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004663

DESCRIPTION

A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to execute arbitrary commands on the underlying Linux operating system with the privilege level of root. The vulnerability is due to insufficient validation of arguments passed to a specific CLI command on the affected device. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability. Cisco NX-OS The software includes OS A command injection vulnerability exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco NX-OS Software is prone to a local command-injection vulnerability. This issue is being tracked by Cisco Bug IDs CSCvh75867, CSCvh75958, CSCvi92239, CSCvi92240, CSCvi92242, CSCvi92243 and CSCvk36294
