CVE-2021-32729

Estado: ModificadaMedia (5.4)—

Una plataforma XWiki es una Plataforma wiki genérica que ofrece servicios de tiempo de ejecución para aplicaciones construidas sobre ella. Se presenta una vulnerabilidad en versiones anteriores a 12.6.88, 12.10.4 y 13.0. El método de servicio script usado para restablecer el registro de fallos de autenticación puede ser ejecutado por cualquier usuario con derechos de script y no requiere derechos de programación.

Leer descripción completaMostrar menos

Un atacante con derechos de script que sea capaz de restablecer el registro de fallos de autenticación podría llevar a cabo un ataque de fuerza bruta, ya que sería capaz de desactivar virtualmente el mecanismo introducido para mitigar esos ataques. El problema ha sido parcheado en versiones 12.6.8, 12.10.4 y 13.0. No se presentan soluciones aparte de la actualización

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

The script service method used to reset the authentication failures record can be executed by any user with Script rights and does not require Programming rights. An attacher with script rights who is able to reset the authentication failure record might perform a brute force attack, since they would be able to virtually deactivate the mechanism introduced to mitigate those attacks.
