TITLE

Cisco FXOS and Cisco NX-OS Software command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004644

DESCRIPTION

A vulnerability in the CLI of Cisco FXOS Software and 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 FXOS and 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. This issue is being tracked by Cisco Bug IDs CSCvh20029, CSCvh20359, CSCvh66202, CSCvh66214, CSCvh66219, CSCvh66243, CSCvh66257, CSCvh66259 and CSCvk30761. 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 Firepower 4100 Series; Firepower 9300 Security Appliances; MDS 9000 Series Multilayer Switches; Nexus 1000V Switch for Microsoft Hyper-V; Nexus 1000V Switch for VMware vSphere; Nexus 3000 Series Switches; 3600 Platform Switches ; Nexus 5500 Platform Switches ; Nexus 5600 Platform Switches ; Nexus 6000 Series Switches ; Nexus 7000 Series Switches ; Nexus 7700 Series Switches ; Nexus 9000 Series Switches in standalone NX-OS mode ; Nexus 9500 R-Series Switching Platform ; UCS 6200 Series Fabric Interconnects; UCS 6300 Series Fabric Interconnects
