TITLE

Cisco FXOS and NX-OS Software command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004579

DESCRIPTION

A vulnerability in the CLI of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to execute arbitrary commands on the underlying operating system of an affected device with elevated privileges. 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. NX-OS versions prior to 8.3(1) are affected. NX-OS versions prior to 8.3(1) are affected. Cisco FXOS and 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 FXOS and NX-OS Software are prone to a local command-injection vulnerability. This issue is being tracked by Cisco Bug IDs CSCvi01431, CSCvi01440, CSCvi92326, CSCvi92328, CSCvi92329 and CSCvi92332. Cisco Firepower 4100 Series, etc. are all products of Cisco (Cisco). Cisco Firepower 4100 Series is a 4100 series firewall device. Cisco Nexus 3000 Series Switches is a 3000 series 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 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
