Impact

BIG-IP

A remote unauthenticated attacker could potentially exploit this
vulnerability by sending a specific crafted URL that includes the
specific target host name and malicious HTML or JavaScript code to a
Configuration utility user, which is then reflected back to the victim
and executed by the web browser. If the exploit is successful, an
attacker can run JavaScript in the context of the currently logged-in
user.

Enterprise Manager, BIG-IQ, iWorkflow, and Traffix SDC
