CVE-2021-37806Public exploitNetwork attack vector

Database disclosure via time-based blind SQL injection

Published Oct 27, 2021 · Updated Aug 4, 2024

SQL injection in PHPGurukul Vehicle Parking Management System 1.0 allows remote attackers to read database data through crafted requests. Affected endpoints pass the editid, viewid, and catename parameters into MySQL queries without neutralizing SQL syntax, allowing injected SLEEP expressions to control response timing. No authentication or user interaction is required, and the documented consequence is database confidentiality loss rather than modification or service interruption.
