CVE-2020-20467Public exploitNetwork attack vector

Authenticated task forgery via trusted creator field

Published Jun 21, 2021 · Updated Aug 4, 2024

Improper authorization in White Shark System 1.3.2 allows remote authenticated users to create tasks attributed to an administrator. The default_task_add.php handler trusts the client-supplied csa_create_user field as the task dispatcher without verifying that identity. A valid session is required, and changing that field to an administrator identifier forges task authorship and alters application data.
