K41704442: BIG-IP-reflected XSS vulnerability in an undisclosed Configuration
utility page CVE-2018-15315

Security Advisory

Original Publication Date: Oct 18, 2018
Updated Date: Oct 23, 2018

Security Advisory Description

A BIG-IP-reflected cross-site scripting (XSS) vulnerability exists in an
undisclosed Configuration utility page. (CVE-2018-15315)

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

There is no impact for these F5 products; they are not affected by this
vulnerability.

Security Advisory Status

F5 Product Development has assigned ID 707990 (BIG-IP) to this vulnerability.
Additionally, BIG-IP iHealth may list Heuristic H41704442 on the Diagnostics >
Identified > Medium page.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.

Mitigation

None. However, newer versions of the Google Chrome and Internet Explorer
browsers include an XSS auditor that is enabled by default. This feature has
the ability to block this vulnerability.
