"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-093024 advisory.

    By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the
    values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be
    included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or
    headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue
    only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default.
    Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized
    SQL queries and further customization over the columns written to in logs. Apache Log4j 1.2 reached end of
    life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the
    previous versions.

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.");
