CVEID:__CVE-2014-0112 __
DESCRIPTION:
Apache Struts could allow a remote attacker to execute arbitrary code on the system, caused by an incomplete fix related to ParametersInterceptor and the failure to restrict access to the class parameter. An attacker could exploit this vulnerability using the class parameter to manipulate the ClassLoader used by the application server to execute arbitrary code on the system.
