Vulnerability from fkie_nvd - Published: 2024-09-13 18:15 - Updated: 2025-07-10 13:23
Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
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 Hence, if a user (whose access to an organization has been revoked) already possesses the organization key, that user could use the key to decrypt the leaked data.

      "value": "Se descubri\u00f3 un problema en Vaultwarden (anteriormente Bitwarden_RS) 1.30.3. Carece de un proceso de desvinculaci\u00f3n para los miembros que abandonan una organizaci\u00f3n. Como resultado, la clave de organizaci\u00f3n 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 organizaci\u00f3n. Adem\u00e1s, la aplicaci\u00f3n no protege adecuadamente algunos datos cifrados almacenados en el servidor. En consecuencia, un usuario autenticado podr\u00eda obtener acceso no autorizado a los datos cifrados de cualquier organizaci\u00f3n, incluso si el usuario no es miembro de la organizaci\u00f3n en cuesti\u00f3n. Sin embargo, el usuario necesitar\u00eda saber el ID de organizaci\u00f3n correspondiente. Por lo tanto, si un usuario (cuyo acceso a una organizaci\u00f3n ha sido revocado) ya posee la clave de la organizaci\u00f3n, ese usuario podr\u00eda usar la clave para descifrar los datos filtrados."
