Vulnerability from fkie_nvd - Published: 2022-12-31 01:15 - Updated: 2025-04-11 15:15
Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
An issue was discovered in Mellium mellium.im/sasl before 0.3.1. When performing SCRAM-based SASL authentication, if the remote end advertises support for channel binding, no random nonce is generated (instead, the nonce is empty). This causes authentication to fail in the best case, but (if paired with a remote end that does not validate the length of the nonce) could lead to insufficient randomness being used during authentication.

Al realizar la autenticaci\u00f3n SASL basada en SCRAM, si el extremo remoto anuncia soporte para enlace de canal, no se genera ning\u00fan nonce aleatorio (en cambio, el nonce est\u00e1 vac\u00edo). Esto hace que la autenticaci\u00f3n falle en el mejor de los casos, pero (si se combina con un extremo remoto que no valida la longitud del nonce) podr\u00eda provocar que se utilice una aleatoriedad insuficiente durante la autenticaci\u00f3n."
