CVE-2024-11820Public exploitNetwork attack vector

Stored cross-site scripting via unfiltered address output

Published Nov 27, 2024 · Updated Nov 27, 2024

Stored cross-site scripting in Code Projects CRUD Operation System 1.0 allows remote authenticated users to inject script through saddress. The add.php handler stores the submitted saddress value, and index.php echoes that database field into a table cell without filtering or output encoding. Low-privileged access is required to create the record, and the script executes when another user opens the listing, enabling actions in that user's browser session.
