Impact

To perform the attack, a user must visit a specially crafted URL that
includes the specific target host name. If the exploit is successful,
an attacker can run JavaScript in the context of the currently
logged-in user. In the case of an administrative user with Advanced
Shell ( bash ) access, successful exploitation of this vulnerability
can be leveraged to completely compromise the BIG-IP system through
Remote Code Execution.");
