Stored script execution via unfiltered column name
Published Dec 22, 2021 · Updated Aug 4, 2024
Stored XSS in MetInfo 7.0 beta allows remote authenticated users to execute script in an administrator's browser via a column name. The doAddColumn method reads $_M['form']['name'], and _addColumn assigns it directly to $sava_data['name'] before database insertion without filtering. Access to the authenticated column-management endpoint and a later page view are required; the injected script runs with the viewing user's web-session privileges.
