Introduction  
=================  
An information disclosure vulnerability in `/be/rpc.php` allows remote authenticated users with the appropriate permissions to modify database connections to disclose the clear text credentials via the `test connection` function. To exploit the vulnerability, the attacker must set the host of the database connection to a server under his control.  
  
  
Write-Up  
=================  
See [Docs Syslifters](https://docs.syslifters.com/) for a detailed write-up on how to exploit vulnerability.  
  
  
Proof of Concept  
=================  
1) The host part of a database connection can be changed in the connections details in the UI. Set the Host to a server that you control.  
  
2) Test the database connection.  
  
3) The webserver initiates a connection to the server that you control. Use wireshark to capture network traffic and to ultimately extract the database credentials.
