CVE-2023-5271Known exploitationPublic exploit

Authenticated SQL injection via email parameter

Published Sep 29, 2023 · Updated Aug 2, 2024

SQL injection in SourceCodester Best Courier Management System 1.0 allows remote authenticated users to alter database data via edit_parcel.php email input. The edit_parcel.php handler incorporates the email argument into a database query without adequate neutralization, so crafted input can inject SQL syntax. Exploitation requires low-privilege access from an adjacent network position; the published impact is limited database disclosure, modification, and service disruption.
