K18535734:BIG-IP Secure Vault vulnerability CVE-2019-6609

Security Advisory

Original Publication Date: 11 Apr, 2019

Security Advisory Description

This vulnerability impacts only the iSeries platforms. On these platforms, the
secureKeyCapable attribute is not set, which causes the Secure Vault feature to
not use F5 hardware support to store the unit key. Instead, the unit key is
stored in plaintext on disk, as is the case for Z100 systems. Additionally,
this issue causes the unit key to be stored in UCS files taken on these
platforms. (CVE-2019-6609)

Impact

BIG-IP

The unit key on a BIG-IP iSeries platform is stored in plaintext. As a result,
the confidentiality of the unit key and master key on the BIG-IP iSeries
platform may be compromised. All other BIG-IP platforms are not affected by
this vulnerability.

Enterprise Manager, BIG-IQ Centralized Management, F5 iWorkflow, Traffix SDC

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

Security Advisory Status

F5 Product Development has assigned ID 737910 (BIG-IP) to this vulnerability.
