"A reflected 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 current logged-in
user. (CVE-2018-15312)

Impact

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
BIG-IP 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. In the case of an administrative user with access to
the Advanced Shell ( bash ), successful exploitation of this
vulnerability can be leveraged to completely compromise the BIG-IP
system through Remote Code Execution.");
