CVE-2023-1827Public exploitNetwork attack vector

Authenticated SQL injection via unfiltered location identifier

Published Apr 4, 2023 · Updated Aug 2, 2024

SQL injection in SourceCodester Centralized Covid Vaccination Records System 1.0 allows remote authenticated users to alter database queries. The manage_location.php handler fails to neutralize quote-delimited predicates supplied through the id GET parameter before SQL execution. A valid PHP session is required; boolean predicates change the response and a MySQL SLEEP expression delays it, enabling database inference.
