Title
BIG-IP Configuration utility vulnerability
Summary
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.
