Summary: Pageflow vulnerable to sensitive user data extraction via Ransack query injection

Details: ### Impact The attack allows extracting sensitive properties of database objects that are associated with users or entries belonging to an account that the attacker has access to. Pageflow uses the `ActiveAdmin` Ruby library to provide some management features to its users. `ActiveAdmin` relies on the `Ransack` library to implement search functionality. In its default configuration, `Ransack` will allow for query conditions based on properties of associated database objects [1]. The `*_starts_with`, `*_ends_with` or `*_contains` search matchers [2] can then be abused to exfiltrate sensitive string values of associated database objects via character-by-character brute-force. [1] https://activerecord-hackery.github.io/ransack/going-further/associations/ [2] https://activerecord-hackery.github.io/ransack/getting-started/search-matches/ ### Mitigation Upgrade to version 15.7.1 or 14.5.2 of the `pageflow` gem. ### For more information If you have any questions or comments about this advisory email us at info(at)codevise.de ### Credits [Positive Security](https://positive.security/)
