Insecure File Permissions and Arbitrary File Upload in the upload pic function in updatesubcategory.php in Projects World Travel Management System v1.0 allows remote unauthenticated attackers to gain remote code execution.

File Upload component in Projects World House Rental v1.0 suffers from an arbitrary file upload vulnerability with regular users, which allows remote attackers to conduct code execution.

Project Worlds Official Car Rental System 1 is vulnerable to multiple SQL injection issues, as demonstrated by the email and parameters (account.php), uname and pass parameters (login.php), and id parameter (book_car.php) This allows an attacker to dump the MySQL database and to bypass the login authentication prompt.

An issue was discovered in Project Worlds Official Car Rental System 1. It allows the admin user to run commands on the server with their account because the upload section on the file-manager page contains an arbitrary file upload vulnerability via add_cars.php. There are no upload restrictions for executable files.
