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

A reflected cross-site scripting (XSS) vulnerability exists in an undisclosed
page of the BIG-IP Configuration utility that allows an attacker to run
JavaScript in the context of the currently logged-in user. (CVE-2024-33604)

Impact

An attacker may exploit this vulnerability by causing an authenticated user to
send a crafted URL that is then reflected back and run by the user’s web
browser. If successful, an attacker can run JavaScript in the context of the
currently logged-in user. In the case of an administrative user with access to
the Advanced Shell (bash), an attacker can leverage successful exploitation of
this vulnerability to compromise the BIG-IP system. This is a control plane
issue; there is no data plane exposure.

Security Advisory Status

F5 Product Development has assigned ID 1492361 (BIG-IP) to this vulnerability.
This issue has been classified as CWE-79: Improper Neutralization of Input
During Web Page Generation (‘Cross-site Scripting’).

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.

BIG-IP Next

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 20.0.2, the fix also applies to 20.0.3, and all later
20.1.x releases. For more information, refer to K51812227: Understanding
security advisory versioning.

^1F5 evaluates only software versions that have not yet reached the End of
Technical Support (EoTS) phase of their lifecycle. For more information, refer
to the Security hotfixes section of K4602: Overview of the F5 security
vulnerability response policy.

BIG-IP and BIG-IQ

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 16.1.2.1, the fix also applies to 16.1.2.2, and all
later 16.1.x releases (16.1.3.x, 16.1.4.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

To mitigate this vulnerability, you may take the following actions:

o When finished using the Configuration utility, log off and close all
instances of the web browser.
o Do not use the same web browser that you use to manage the BIG-IP
Configuration utility for any other purposes, such as browsing the
Internet. If you must perform both actions on the same client machine, do
so in separate browsers.

Acknowledgments

This issue was discovered internally by F5.
