CVE-2022-31177

Flask-AppBuilder is an application development framework built on top of Flask python framework. In versions prior to 4.1.3 an authenticated Admin user could query other users by their salted and hashed passwords strings. These filters could be made by using partial hashed password strings. The response would not include the hashed passwords, but an attacker could infer partial password hashes and their respective users. This issue has been fixed in version 4.1.3. Users are advised to upgrade. There are no known workarounds for this issue.

### Impact An authenticated Admin user could craft HTTP requests to filter users by their salted and hashed passwords strings. These filters could be made by using partial hashed password strings. The response would not include the hashed passwords, but an attacker could infer partial password hashes and their respective users. Only when using `AUTH_DB` database authentication option. ### Patches Fixed on 4.1.3 ### For more information If you have any questions or comments about this advisory: * Open an issue in [example link to repo](http://example.com) * Email us at [example email address](mailto:example@example.com)

Flask-AppBuilder es un marco de desarrollo de aplicaciones construido sobre el marco de trabajo python Flask. En versiones anteriores a 4.1.3, un usuario administrador autenticado podía consultar a otros usuarios por sus cadenas de contraseñas con sal y hash. Estos filtros podían hacerse al usar cadenas de contraseñas con hash parcial. La respuesta no incluiría las contraseñas con hash, pero un atacante podría inferir los hash de las contraseñas parciales y sus respectivos usuarios. Este problema ha sido corregido en versión 4.1.3. Es recomendado a usuarios actualizar. No se presentan mitigaciones conocidas para este problema
