TITLE

Cisco FXOS and Cisco NX-OS Software command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004661

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 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 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 CSCvh20027, CSCvh20389, CSCvi01445, CSCvi01448, CSCvi91985, CSCvi92126, CSCvi92128, CSCvi92129, CSCvi92130, CSCvi96522, CSCvi96524, CSCvi96525, CSCvi96526 and CSCvi96527. Both Cisco NX-OS Software and Cisco FXOS Software are products of Cisco (Cisco). 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 3000 Series Switches ; Nexus 3500 Platform Switches ; Nexus 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
