CVE-2022-30391Public exploitNetwork attack vector

Database-name disclosure via injectable category identifier

Published May 13, 2022 · Updated Aug 3, 2024

SQL injection in Merchandise Online Store 1.0 allows remote attackers to disclose the database name through the delete-category endpoint. The delete_category action in classes/Master.php passes the POST id value to a database operation without neutralizing SQL syntax, as demonstrated by an updatexml payload. The published request uses the administrative category-maintenance flow and a PHP session cookie; public evidence does not establish whether authentication is enforced or whether broader database access was demonstrated.
