Technical details

A SQL injection vulnerability exists in CodeAstro Simple Online Leave Management System 1.0 within the '/SimpleOnlineLeave/admin/dashboard.php' file. The root cause is the improper neutralization of special elements in the 'Name' POST parameter, which is used directly in SQL queries without adequate validation or prepared statements. A remote attacker with low-level privileges can exploit this via time-based blind SQL injection (e.g., using the SLEEP function) to extract sensitive data or manipulate the database. A public exploit (PoC) using sqlmap has been disclosed. No official patch is currently documented, but remediation should involve implementing prepared statements with parameter binding.
