"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-589226 advisory.

    Improper Access Control vulnerability in Apache Commons.



    A special BeanIntrospector class was added in version 1.9.2. This can be used to stop attackers from using
    the declared class property of Java enum objects to get access to the classloader. However this protection
    was not enabled by default. PropertyUtilsBean (and consequently BeanUtilsBean) now disallows declared
    class level property access by default.





    Releases 1.11.0 and 2.0.0-M2 address a potential security issue when accessing enum properties in an
    uncontrolled way. If an application using Commons BeanUtils passes property paths from an external source
    directly to the getProperty() method of PropertyUtilsBean, an attacker can access the enums class
    loader via the declaredClass property available on all Java enum objects. Accessing the
    enums declaredClass allows remote attackers to access the ClassLoader and execute arbitrary code.
    The same issue exists with PropertyUtilsBean.getNestedProperty().
    Starting in versions 1.11.0 and 2.0.0-M2 a special BeanIntrospector suppresses the declaredClass
    property. Note that this new BeanIntrospector is enabled by default, but you can disable it to regain the
    old behavior; see section 2.5 of the user's guide and the unit tests.

    This issue affects Apache Commons BeanUtils 1.x before 1.11.0, and 2.x before 2.0.0-M2.Users of the
    artifact commons-beanutils:commons-beanutils

     1.x are recommended to upgrade to version 1.11.0, which fixes the issue.


    Users of the artifact org.apache.commons:commons-beanutils2

     2.x are recommended to upgrade to version 2.0.0-M2, which fixes 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.");
