TITLE

Cisco NX-OS Software command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004730

DESCRIPTION

A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker 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 contains a command injection vulnerability.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 ID and CSCvi42292, CSCvj12273 and CSCvj12274. This vulnerability stems from the fact that the network system or product does not correctly filter special elements in the process of constructing executable commands from external input data. The following products and versions are affected: Cisco Nexus 5500 Platform Switches; Nexus 5600 Platform Switches; Nexus 6000 Series Switches; Nexus 7000 Series Switches; Nexus 7700 Series Switches;
