Description

A vulnerability in certain CLI commands of Cisco Identity Services Engine (ISE) could allow an authenticated, local attacker to execute arbitrary commands on the host operating system with the privileges of the local user, aka Command Injection. These commands should have been restricted from this user. The vulnerability is due to insufficient input validation of CLI command user input. An attacker could exploit this vulnerability by authenticating to the targeted device and issuing a CLI command with crafted user input. A successful exploit could allow the attacker to execute arbitrary commands on the affected system that should be restricted. The attacker would need to have valid user credentials for the device. Cisco Bug IDs: CSCvf49844.

• CWE-20Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
• 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.
