Description

A vulnerability in the web management interface of the Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system. The vulnerability is due to insufficient validation of user-supplied parameters for certain API endpoints. An attacker could exploit this vulnerability by sending crafted input to an affected API endpoint. A successful exploit could allow an attacker to execute arbitrary commands on the device with low system privileges. To successfully exploit this vulnerability, an attacker would need valid credentials for a user with Device permissions: by default, only Administrators, Security Approvers and Network Admins user accounts have these permissions.

• 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.
