CVE-2025-4112Public exploitNetwork attack vector

Unauthenticated SQL injection via unsanitized course-short input

Published Apr 30, 2025 · Updated Apr 30, 2025

SQL injection in Projectworlds Student Record System 3.20 allows remote attackers to manipulate its database through a crafted course-short value. The /add-course.php handler places the POST parameter directly into an SQL query without sanitization or validation. No login is required, and the published time-based blind proof of concept uses a MySQL SLEEP expression to demonstrate query control.
