| Vetor | AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N |
Name of the Vulnerable Software and Affected Versions
Parse Server versions prior to 8.6.60
Parse Server versions prior to 9.6.0-alpha.54
Description
An attacker with a user's password and a valid multi-factor authentication (MFA) recovery code can reuse the recovery code an unlimited number of times by sending concurrent login requests. This circumvents the intended single-use functionality of recovery codes. The attack requires the user's password, a valid recovery code, and the ability to send requests rapidly. The issue stems from a lack of proper handling of single-use tokens during login attempts. The login handler did not employ optimistic locking when updating authentication data containing consumed single-use tokens, allowing concurrent requests to bypass the single-use restriction.
Recommendations
Update to Parse Server version 8.6.60 or later.
Update to Parse Server version 9.6.0-alpha.54 or later.
