CVE-2023-3340Public exploitNetwork attack vector

Authenticated SQL injection via name_startsWith parameter

Published Jun 20, 2023 · Updated Aug 2, 2024

SQL injection in ajx.php in SourceCodester Online School Fees System 1.0 allows remote authenticated users to manipulate database queries. The handler places name_startsWith into a database query without neutralizing SQL syntax, and a UNION SELECT payload returns an injected marker. Low-privileged access is required; the demonstrated oracle confirms attacker-controlled query composition, but public evidence does not establish full database control.
