K08182564: BIG-IP SIP profile vulnerability CVE-2023-22842
Published Date: Feb 1, 2023
Updated Date: Feb 3, 2023
Final- This article is marked as 'Final' because the security issue described
in this article either affected F5 products at one time and was resolved or it
never affected F5 products. Unless new information is discovered, F5 will no
longer update the article.
Security Advisory Description
When a SIP profile is configured on a Message Routing type virtual server,
undisclosed traffic can cause the Traffic Management Microkernel (TMM) to
terminate. (CVE-2023-22842)
Impact
Traffic is disrupted while the TMM process restarts. This vulnerability allows
a remote unauthenticated attacker to cause a denial-of-service (DoS) on the
BIG-IP system. There is no control plane exposure; this is a data plane issue
only.
Security Advisory Status
F5 Product Development has assigned ID 1083225 (BIG-IP) to this vulnerability.
This issue has been classified as CWE-121: Stack-based Buffer Overflow.
To determine if your product and version have been evaluated for this
vulnerability, refer to the Evaluated products 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, point releases, or
hotfixes that address the vulnerability, refer to the following tables. You can
also use iHealth to diagnose a vulnerability for BIG-IP and BIG-IQ systems. For
more information about using iHealth, refer to K27404821: Using F5 iHealth to
diagnose vulnerabilities. For more information about security advisory
versioning, refer to K51812227: Understanding security advisory versioning.

Note: After a fix is introduced for a given minor branch, that fix applies to
all subsequent maintenance and point releases for that branch, and no
additional fixes for that branch will be listed in the table. For example, when
a fix is introduced in 14.1.2.3, the fix also applies to 14.1.2.4, and all
later 14.1.x releases (14.1.3.x., 14.1.4.x). For more information, 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 installing a version listed in
the Fixes introduced in column. If the Fixes introduced in column does not list
a version for your branch, then no update candidate currently exists for that
branch and F5 recommends that you upgrade to a version with the fix (refer to
the tables).
If the Fixes introduced in column lists a version prior to the one you are
running, in the same branch, then your version should have the fix.
Mitigation
None
