EMC Unisphere for VMAX Virtual Appliance prior to 8.2.0


EMC Unisphere for VMAX Virtual Appliance contains a fix for an arbitrary file
upload vulnerability. This vulnerability could expose the VMAX Virtual 
Appliance to be potentially compromised by malicious users.


EMC Unisphere for VMAX Virtual Appliance is affected by an Arbitrary File 
Upload vulnerability. A certain HTTP servlet in vApp Manager accepts files 
from an unauthenticated client and uses the file path provided by the client 
to form the path on the server and writes the file to that path as the root 
user. An attacker could exploit this scenario to write arbitrary files to 
arbitrary paths as root user and compromise the system.


The following EMC Unisphere for VMAX Virtual Appliance release contains 
resolution to this vulnerability:
