EMC CMCNE 11.2.1 Inmservlets.war FileUploadController Remote Code Execution
Posted Sep 14, 2017
Authored by James Fitts | Site metasploit.com

This Metasploit module exploits a file upload vulnerability found in EMC Connectrix Manager Converged Network Edition <= 11.2.1. The file upload vulnerability is triggered when sending a specially crafted filename to the FileUploadController servlet found within the Inmservlets.war archive. This allows the attacker to upload a specially crafted file which leads to remote code execution in the context of the server user.
