"A privilege escalation vulnerability exists in ManageEngine AssetExplorer prior to 6.9 Build 6981. 
This vulnerability allows an adversary to access restricted data in the Postgres database setup by 
using a specific PostgreSQL function in the query, which enables bypassing the validation mechanism.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version   
number.");
