🚨 A crafty attacker could drop a remote shell just by uploading a file! The PHPGurukul Car Rental Project version 2.0 has a vulnerability in changeimage1.php that makes this possible. 🔥 Think of it like a hotel that lets guests check in with any unverified luggage — one bag could contain anything, even a thief's tools! In this case, a malicious file can be uploaded without proper validation, opening the door to mischief. If exploited, this vulnerability could allow an attacker to execute arbitrary commands on the server, potentially leading to a complete takeover of the system. Imagine a rogue guest rummaging through the entire hotel, altering bookings, accessing secure areas, or worse.
