TITLE

Cisco NX-OS Software command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004530

DESCRIPTION

A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local 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 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 user 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 is prone to a local command-injection vulnerability. This issue is being tracked by Cisco Bug ID CSCvi42373 and CSCvj12009. Cisco NX-OS Software is a data center-level operating system software used by a set of switches of Cisco. A command injection vulnerability exists in the CLI in Cisco NX-OS Software. 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: MDS 9000 Series Multilayer Switches; Nexus 1000 Virtual Edge; Nexus 1000V Switch for Microsoft Hyper-V; Nexus 1000V Switch for VMware vSphere; Nexus 3000 Series Switches; Nexus 3500 Platform Switches; Nexus 3600 Platform Switches 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; UCS 6400 Series Fabric Interconnects
