Description

A vulnerability in Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system (OS) of an affected device as root. The vulnerability is due to insufficient input validation of a configuration file that is accessible to a local shell user. An attacker could exploit this vulnerability by including malicious input during the execution of this file. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS as root.

• CWE-77Improper Neutralization of Special Elements used in a Command ('Command Injection')The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
• CWE-78Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
