K68151373:IP Intelligence Feed List TMUI vulnerability CVE-2019-6636
Security Advisory
Original Publication Date: 02 Jul, 2019
Security Advisory Description
Stored cross-site scripting vulnerability in AFM feed list. In the worst case,
an attacker can store a CSRF which results in code execution as the admin user.
The level of user role which can perform this attack are resource
administrator and administrator. (CVE-2019-6636)
Impact
The particular scenario of concern is that a resource administrator who is not
granted an Advanced Shell (bash) can use this flaw to store an attack, which
will run shell commands when an admin with bash browses to the particular Feed
List page that hosts the exploit code. While the stored CSRF is possible in
non-appliance and appliance mode systems, running shell commands is not
possible if the system is configured in appliance mode, since there is no shell
available.

K29149494:iControl REST vulnerability CVE-2019-6637
Security Advisory
Original Publication Date: 02 Jul, 2019
Security Advisory Description
Application logic abuse of ASM REST endpoints can lead to instability of BIG-IP
system. Exploitation of this issue causes excessive memory consumption which
results in the Linux kernel triggering OOM killer on arbitrary processes. The
attack requires an authenticated user with role of "Guest" or greater
privilege. Note: "No Access" cannot login so technically it's a role but a user
with this access role cannot perform the attack. (CVE-2019-6637)
Impact
BIG-IP ASM
When the vulnerability is exploited, the affected BIG-IP ASM system may
experience excessive memory consumption to the point where the Linux kernel
triggers OOM killer, resulting in a possible denial-of-service (DoS).
BIG-IP (LTM, AAM, AFM, Analytics, APM, DNS, Edge Gateway, FPS, GTM, Link
Controller, PEM, WebAccelerator) / BIG-IQ / Enterprise Manager / F5 iWorkflow /
Traffix SDC
There is no impact; these F5 products are not affected by this vulnerability.

K20541896:iControl REST and tmsh vulnerability CVE-2019-6621
Security Advisory
Original Publication Date: 02 Jul, 2019
Security Advisory Description
Undisclosed iControl REST worker is vulnerable to command injection by an admin
/resource admin user. This issue impacts both iControl REST and tmsh
implementations. (CVE-2019-6621)
Impact
BIG-IP / BIG-IQ
This vulnerability may bypass appliance mode security by allowing the execution
of arbitrary bash commands. In non-Appliance mode deployments, the
Administrator and Resource Administrator users already own this level of
access. F5 considers this vulnerability a security concern primarily for
systems deployed in Appliance mode. In addition, a valid attack vector exists
for users who are not already granted Advanced Shell (bash) access, such as a
Resource Administrator, who by default is not explicitly granted bash access.
Enterprise Manager / 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 737574 (BIG-IP), and ID 746610 (BIG-IQ)
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

K79902360:BIG-IP TMUI vulnerability CVE-2019-6625
Security Advisory
Original Publication Date: 02 Jul, 2019
Security Advisory Description
A reflected cross-site scripting (XSS) vulnerability exists in an undisclosed
page of the BIG-IP Traffic Management User Interface (TMUI) also known as the
BIG-IP Configuration utility. (CVE-2019-6625)
Impact
To perform the attack, a user must visit a specially crafted URL that includes
the specific target host name. If the exploit is successful, an attacker can
run JavaScript in the context of the currently logged-in user. In the case of
an administrative user with Advanced Shell (bash) access, successful
exploitation of this vulnerability can be leveraged to completely compromise
the BIG-IP system through Remote Code Execution.
Security Advisory Status
F5 Product Development has assigned ID 754345 (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

K44885536:iControl REST vulnerability CVE-2019-6622
Security Advisory
Original Publication Date: 02 Jul, 2019
Security Advisory Description
Undisclosed iControl REST worker is vulnerable to command injection by an
administrator or resource administrator user. This attack is only exploitable
on multi-bladed systems.
The vulnerability allows bypass of Appliance mode security on BIG-IP systems by
allowing the execution of arbitrary Advanced Shell (bash) commands. In systems
without Appliance mode security, the administrator and resource administrator
users will likely have this level of access already. F5 considers this a
security concern mostly for systems deployed in Appliance mode, but it's also a
valid attack vector for users that do not already have bash access granted. For
example, a resource administrator who does not already have bash access
explicitly granted in the user configuration can be exploited as an attack
vector. (CVE-2019-6622)
Impact
A remote attacker can exploit the vulnerability by executing arbitrary bash
commands on a vulnerable multi-bladed system.
Security Advisory Status
F5 Product Development has assigned ID 737731 (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
