File upload vulnerability in WebErpMesv2 1.17 in the app/Http/Controllers/FactoryController.php controller. This flaw allows an authenticated attacker to upload arbitrary files, including PHP scripts, which can be accessed via direct GET requests, potentially resulting in remote code execution (RCE) on the web server.
The PHP application uses an old method for processing uploaded files by referencing the four global variables that are set for each file (e.g. $varname, $varname_size, $varname_name, $varname_type). These variables could be overwritten by attackers, causing the application to process unauthorized files.
