K20682450:BIG-IP AFM vulnerability CVE-2017-6142

Security Advisory

Original Publication Date: 19 Jan, 2018

Latest   Publication Date: 04 Apr, 2018

Security Advisory Description

X509 certificate verification was not correctly implemented in the early
access "user id" feature in the BIG-IP Advanced Firewall Manager, and thus did
not properly validate the remote server's identity on certain versions of
BIG-IP. (CVE-2017-6142)

Impact

In affected BIG-IP AFM versions, the system is unable to properly validate the
remote server's identity, which may lead to man-in-the-middle (MITM) attacks.
This issue affects the Network Firewall policy enforcement. The issue depends
on an experimental configuration that was only deployed with F5 technical
assistance as a proof of concept.
