CVE-2024-39925

Estado: AnalizadaMedia (6.5)—

An issue was discovered in Vaultwarden (formerly Bitwarden_RS) 1.30.3. It lacks an offboarding process for members who leave an organization. As a result, the shared organization key is not rotated when a member departs. Consequently, the departing member, whose access should be revoked, retains a copy of the organization key. Additionally, the application fails to adequately protect some encrypted data stored on the server. Consequently, an authenticated user could gain unauthorized access to encrypted data of any organization, even if the user is not a member of the targeted organization.

However, the user would need to know the corresponding organizationId. Hence, if a user (whose access to an organization has been revoked) already possesses the organization key, that user could use the key to decrypt the leaked data.

Como resultado, la clave de organización compartida no se rota cuando un miembro se va. En consecuencia, el miembro que se va, cuyo acceso debe revocarse, conserva una copia de la clave de la organización. Además, la aplicación no protege adecuadamente algunos datos cifrados almacenados en el servidor. En consecuencia, un usuario autenticado podría obtener acceso no autorizado a los datos cifrados de cualquier organización, incluso si el usuario no es miembro de la organización en cuestión. Sin embargo, el usuario necesitaría saber el ID de organización correspondiente. Por lo tanto, si un usuario (cuyo acceso a una organización ha sido revocado) ya posee la clave de la organización, ese usuario podría usar la clave para descifrar los datos filtrados."
