Description David Jorm 2014-07-07 02:03:37 UTC
It was found that commons-beanutils exposes the class property by default, with no mechanism to disable access to it. If a framework built on commons-beanutils does not otherwise suppress access to the class property, then a remote attacker could use this flaw to manipulate the ClassLoader used by the underlying container. This could lead to remote code execution under certain conditions.

Comment 1 David Jorm 2014-07-07 02:30:32 UTC

MITRE has rejected this CVE ID, favoring the use of CVE-2014-0114.

This flaw was the root cause of CVE-2014-0114, a flaw in Apache Struts 1 that could lead to unauthenticated remote code execution under certains conditions. Other frameworks built on commons-beanutils, such as Apache Stripes, are likely to expose similar issues. commons-beanutils 1.9.2 has now shipped, including a specialized BeanIntrospector implementation that allows suppressing properties. Frameworks built on commons-beantutils can make use of the new pre-configured SuppressPropertiesBeanIntrospector to address this flaw.
