K49622415: Apache Tomcat vulnerability CVE-2022-25762
Original Publication Date: 08 Jul, 2022
Security Advisory Description
If a web application sends a WebSocket message concurrently with the WebSocket
connection closing when running on Apache Tomcat 8.5.0 to 8.5.75 or Apache
Tomcat 9.0.0.M1 to 9.0.20, it is possible that the application will continue to
use the socket after it has been closed. The error handling triggered in this
case could cause the a pooled object to be placed in the pool twice. This could
result in subsequent connections using the same object concurrently which could
result in data being returned to the wrong use and/or other errors. (
CVE-2022-25762)
Impact
A remote attacker may be able to exploit this vulnerability to compromise the
data confidentiality, integrity, and availability of the affected system.
Security Advisory Status
F5 Product Development has assigned SDC-1988 and SDC-1989 (Traffix SDC) 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, point 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.
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. Additionally, software
versions preceding those listed in the Applies to (see versions) box of this
article have reached the End of Technical Support (EoTS) phase of their
lifecycle and are no longer evaluated for security issues. For more
information, refer to the Security hotfixes section of K4602: Overview of the
F5 security vulnerability response policy.

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 upgrading to a version with the fix (refer to the
table).
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
To mitigate this vulnerability, you should permit access to the WebUI only over
a secure network and limit login access to trusted users.
