Amazon Linux 2023 : apache-commons-beanutils, apache-commons-beanutils-javadoc (ALAS2023-2025-999)

high Nessus Plugin ID 238283

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-999 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 enum's class loader via the declaredClass property available on all Java enum objects. Accessing the enum's 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. (CVE-2025-48734)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'dnf update apache-commons-beanutils --releasever 2023.7.20250609' to update your system.
