QID 377807

A stored cross-site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility that allows an attacker to execute JavaScript in the context of the currently logged-in user.

Vulnerable Component:
BIG-IP AFM,CGNAT,PEM

Affected Versions:
16.1.0 - 16.1.2
15.1.0 - 15.1.5
14.1.0 - 14.1.4
13.1.0. - 13.1.4
12.1.0. - 12.1.6
11.6.1. - 11.6.5

QID Detection Logic(Authenticated):
This QID checks for the vulnerable versions of F5 BIG-IP devices using the tmsh command.

An attacker may exploit this vulnerability by causing an authenticated user to submit malicious HTML or JavaScript code in the BIG-IP Configuration utility. If successful, an attacker can run JavaScript in the context of the currently logged-in user. In the case of an administrative user with access to the Advanced Shell (bash), an attacker can leverage successful exploitation of this vulnerability to compromise the BIG-IP system. This is a control plane issue; there is no data plane exposure.
