Description

A vulnerability exists in an undisclosed BIG-IP Configuration utility page that may allow an attacker to spoof error messages Impact: An attacker may trick authenticated BIG-IP users into accessing malicious links and reflect a spoofed error message in the victim's BIG-IP Configuration utility web browser session. This is a control plane issue; there is no data plane exposure. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

CWE-451

User Interface (UI) Misrepresentation of Critical Information

The user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.
