How the CVE Works
CVE-2025-50348 exploits a directory traversal vulnerability in PHPGurukul’s Pre-School Enrollment System (v1.0) via the `update-class-pic.php` component. The flaw allows attackers to bypass file system restrictions by manipulating input parameters with `../` sequences, enabling unauthorized access to sensitive files outside the web root. This occurs due to improper sanitization of user-supplied paths when handling file uploads or modifications. Successful exploitation could lead to remote code execution, data leakage, or system compromise by accessing /etc/passwd, configuration files, or other critical system resources.
