Tenable Identity Exposure fixes SYSTEM command injection in its AD events listener

Tenable Identity Exposure fixes three flaws, including authenticated command injection that can run as SYSTEM on the PDC emulator. Upgrade to 3.93.6 or 3.77.18, then uninstall and reinstall the IoA script on domain controllers: upgrading alone retains the vulnerable listener.

The advisory reports fixes, not confirmed real-world exploitation.

What happened

The primary advisory lists versions 3.93.5 and earlier and 3.77.17 and earlier as affected. The release notes narrow the command-injection prerequisite to an account able to write the IoA configuration; this is not an unauthenticated domain-controller takeover. The advisory gives CVSS 3.1 scores of 9.9, 4.3 and 4.1, and separate CVSS 4.0 scores of 9.4, 5.3 and 5.6.

Both fixed-release notes require the post-upgrade IoA uninstall/reinstall and warn about custom RSA certificates below 2048 bits. They also describe a separate internal-request error-message disclosure fix without assigning another CVE on this advisory page. No exploitation, victim count or incident-specific indicator list is provided. Review permissions and credential exposure as well as the installed product version.
