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.
A flaw was found in Apache Commons BeanUtils. This vulnerability allows remote attackers to execute arbitrary code via uncontrolled access to the declaredClass property on Java enum objects, which can expose the class loader when property paths are passed from external sources to methods like getProperty() or getNestedProperty().
Отчет
This vulnerability is rated as important severity because a flaw exists in Apache Commons BeanUtils, where PropertyUtilsBean and BeanUtilsBean allow uncontrolled access to the declaredClass property of Java enum objects. Applications that pass untrusted property paths directly to getProperty() or getNestedProperty() methods are at risk, as attackers can exploit this behavior to retrieve the ClassLoader instance and execute arbitrary code in the context of the affected application. This issue leads to compromise of confidentiality, integrity, and availability.
