Descriptions

In GNU Mailman before 2.1.38, a list member or moderator can get a CSRF token and craft an admin request (using that token) to set a new admin password or make other changes.

En GNU Mailman versiones anteriores a 2.1.38, un miembro o moderador de la lista puede conseguir un token de tipo CSRF y diseñar una petición de administración (usando ese token) para establecer una nueva contraseña de administrador o hacer otros cambios

A Cross-Site Request Forgery (CSRF) attack can be performed in mailman due to a CSRF token bypass. CSRF tokens are not checked against the right type of user when performing admin operations and a token created by a regular user can be used by an admin to perform an admin-level request, effectively bypassing the protection provided by CSRF tokens. A remote attacker with an account on the mailman system can use this flaw to perform a CSRF attack and perform operations on behalf of the victim admin.
