Description

This module exploits a remote command execution vulnerability in Apache Struts versions
1.x ( the ActionForm bean population mechanism while in case of Struts 2.x the vulnerability is due
to the ParametersInterceptor. Both allow access to 'class' parameter that is directly
mapped to getClass() method and allows ClassLoader manipulation. As a result, this can
allow remote attackers to execute arbitrary Java code via crafted parameters.
