TITLE

Cisco NX-OS In software OS Command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004603

DESCRIPTION

A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of arguments passed to certain CLI commands. 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 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 multiple local command-injection vulnerabilities. These issues are being tracked by Cisco Bug IDs CSCvh75895, CSCvh75909, CSCvh75968, CSCvh75976, CSCvi92256, CSCvi92258, CSCvi92260, CSCvi99195, CSCvi99197 and CSCvi99198. The vulnerability stems from the fact that the network system or product does not correctly filter special characters, commands, etc. in the process of constructing executable commands of the operating system from external input data. The following products and versions are affected: Cisco MDS 9000 Series Multilayer Switches; Nexus 3000 Series Switches; Nexus 3500 Platform Switches; Nexus 3600 Platform Switches; Nexus 5500 Platform Switches; Nexus 5600 Platform Switches; 7700 Series Switches; Nexus 9000 Series Switches in standalone NX-OS mode; Nexus 9500 R-Series Switching Platform
