K73522927:BIG-IP Appliance mode vulnerability CVE-2019-6633
Security Advisory
Original Publication Date: 02 Jul, 2019
Security Advisory Description
When the BIG-IP system is licensed with Appliance mode, user accounts with
Administrator and Resource Administrator roles can bypass Appliance mode
restrictions. (CVE-2019-6633)
Impact
This vulnerability allows the attacker to exploit the system with high-level
privileges to read and modify the arbitrary files. This behavior is possible
only when the BIG-IP system runs in Appliance mode and the user account is
configured with the Administrator or Resource Administrator role. The Resource
Administrator role requires TMOS Shell (tmsh) access to be vulnerable.
Appliance mode is a licensed feature on the BIG-IP product.
Security Advisory Status
F5 Product Development has assigned ID 702469 (BIG-IP) to this vulnerability.
To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if your
release is known to be vulnerable, the components or features that are affected
by the vulnerability, and for information about releases or hotfixes that
address the vulnerability, refer to the following table. For more information
about security advisory versioning, refer to K51812227: Understanding Security
Advisory versioning.

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.

K11330536:BIG-IP Appliance mode vulnerability CVE-2019-6635
Security Advisory
Original Publication Date: 02 Jul, 2019
Security Advisory Description
When the BIG-IP system is licensed for Appliance mode, a user with either the
Administrator or the Resource Administrator role can bypass Appliance mode
restrictions. (CVE-2019-6635)
Impact
BIG-IP
This vulnerability allows local attackers with high-level privileges to
overwrite arbitrary files. This behavior is possible only when the BIG-IP
system runs in Appliance mode on any of the hardware platforms, and the user
account is configured with Administrator or Resource Administrator role.
Resource Administrator roles must have TMOS Shell (tmsh) access to perform the
attack. Appliance mode is a licensed feature. This vulnerability does not
affect the virtual platforms.
Enterprise Manager / BIG-IQ / F5 iWorkflow / Traffix SDC
There is no impact; F5 products are not affected by this vulnerability.
Security Advisory Status
F5 Product Development has assigned ID 742226 (BIG-IP) to this vulnerability.
To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if your
release is known to be vulnerable, the components or features that are affected
by the vulnerability, and for information about releases or hotfixes that
