Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kafka (UTSA-2026-150469)

high Nessus Plugin ID 376603

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-2026-150469 advisory.

In CVE-2023-25194, we announced the RCE/Denial of service attack via SASL JAAS JndiLoginModule configuration in Kafka Connect API. But not only Kafka Connect API is vulnerable to this attack, the Apache Kafka brokers also have this vulnerability. To exploit this vulnerability, the attacker needs to be able to connect to the Kafka cluster and have the AlterConfigs permission on the cluster resource.

Since Apache Kafka 3.4.0, we have added a system property (-Dorg.apache.kafka.disallowed.login.modules) to disable the problematic login modules usage in SASL JAAS configuration. Also by default com.sun.security.auth.module.JndiLoginModule is disabled in Apache Kafka 3.4.0, and com.sun.security.auth.module.JndiLoginModule,com.sun.security.auth.module.LdapLoginModule is disabled by default in in Apache Kafka 3.9.1/4.0.0

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 kafka package.
