HPE iMC 7.3 Remote Code Execution

HPE iMC 7.3 Remote Code Execution
Posted May 18, 2018
Authored by mr_me, trendytofu | Site metasploit.com

This Metasploit module exploits an expression language injection vulnerability, 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 Metasploit module has been tested successfully on iMC PLAT v7.3(E0504P02) on Windows 2k12r2 x64 (EN).

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

listens on TCP port 8080 and 8443 by default.
