K00174195: Apache Tomcat vulnerability CVE-2021-25122

Original Publication Date: 16 Mar, 2021

Security Advisory Description

When responding to new h2c connection requests, Apache Tomcat versions
10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41 and 8.5.0 to 8.5.61 could duplicate
request headers and a limited amount of request body from one request to
another meaning user A and user B could both see the results of user A's
request. (CVE-2021-25122)

Impact

This vulnerability may lead to exposure of sensitive information to an
unauthorized actor.

Security Advisory Status

F5 Product Development has assigned ID SDC-1029 (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 vulnerable version, that fix applies to
all subsequent point releases for that version and no additional fixes for that
version will be listed in the table. For example, when a fix is introduced in
14.1.2.3, the fix applies to 14.1.2.4 and all later point releases.

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

None
