sol21485342: Configuration utility CSRF vulnerability

Security Advisory

Original Publication Date: 11/08/2016

Vulnerability Description

When an authenticated Configuration utility user visits a specially crafted
web page, the user's current session can be logged out and unknowingly
logged in to the Configuration utility using a different user account.

Impact

When exploited, the authenticated Configuration utility user's login session
is replaced by another user account without the targeted user's knowledge. To
exploit this cross-site request forgery (CSRF) vulnerability, an attacker
must already know the login credentials of a legitimate Configuration
utility user account.

Security Issue Status

F5 Product Development has assigned ID 418664 (BIG-IP) and ID 618353
(Enterprise Manager) to this vulnerability.

Vulnerability 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 Versions known to be not vulnerable 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

To mitigate this vulnerability for affected F5 products, you should only
permit management access to F5 products over a secure network and limit
shell access to trusted users. For more information about securing access to
BIG-IP/Enterprise Manager systems, refer to SOL13309: Restricting access to
the Configuration utility by source IP address (11.x - 12.x) and SOL13092:
Overview of securing access to the BIG-IP system.
