Affected Packages

Package Vulnerable Unaffected -------------------------- ------------ ------------ dev-java/commons-beanutils < 1.11.0 >= 1.11.0

Impact

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.

Workaround

There is no known workaround at this time.
