Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: tomcat (UTSA-2026-130100)

critical Nessus Plugin ID 365876

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-130100 advisory.

 Unchecked Error Condition vulnerability in Apache Tomcat. If Tomcat is configured to use a custom Jakarta Authentication (formerly JASPIC)ServerAuthContext component which may throw an exception during the authentication process without explicitly setting an HTTP status to indicate failure, the authentication may not fail, allowing the user to bypass the authentication process. There are no known JakartaAuthentication components that behave in this way.

 This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M26, from 10.1.0-M1 through 10.1.30, from 9.0.0-M1 through 9.0.95.

 The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100.Other EOL versions may also be affected.


 Users are recommended to upgrade to version 11.0.0, 10.1.31 or 9.0.96, which fix the issue.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected tomcat package.
