🚨 Uploading files has never been this risky! Victor CMS 1.0 lets authenticated users upload malicious PHP files via the profile image feature—an open invitation to chaos! ⚡ Think of it like a restaurant that allows diners to bring in their own ingredients—sure, some may bring delicious recipes, but others might sneak in spoiled items that could ruin the entire meal. In this case, that ‘dish’ is a PHP shell planted on the server! An attacker could easily upload a PHP shell to the /img directory, allowing them to execute system commands through their web browser. This could lead to unauthorized access, data breaches, and complete server control—an absolutely devastating scenario!
