TITLE

Cisco NX-OS Software command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004642

DESCRIPTION

A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker with valid administrator credentials to execute arbitrary commands 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 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 IDs CSCvh20096, CSCvh20112, CSCvi96504, CSCvi96509 and CSCvi96510. Cisco Nexus 3000 Series Switches are all products of Cisco (Cisco). Cisco Nexus 3000 Series Switches is a 3000 series switch. Cisco Nexus 3500 Platform Switches is a 3500 series platform switch. Cisco MDS 9000 Series Multilayer Switches is a MDS 9000 series multilayer switch. 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 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; UCS 6200 Series Fabric Interconnects; UCS 6300 Series Fabric Interconnects
