Descriptions

An issue was discovered in the AbuseFilter extension for MediaWiki through 1.35.2. It incorrectly executed certain rules related to blocking accounts after account creation. Such rules would allow for user accounts to be created while blocking only the IP address used to create an account (and not the user account itself). Such rules could also be used by a nefarious, unprivileged user to catalog and enumerate any number of IP addresses related to these account creations.

Se detectó un problema en la extensión AbuseFilter para MediaWiki versiones hasta 1.35.2. Ejecutó inapropiadamente determinadas reglas relacionadas con el bloqueo de cuentas después de la creación de la cuenta. Dichas reglas permitirían crear cuentas de usuario mientras se bloquea solo la dirección IP usada para crear una cuenta (y no la cuenta de usuario en sí). Estas reglas también podrían ser usadas por un usuario infame y sin privilegios para catalogar y enumerar cualquier número de direcciones IP relacionadas con estas creaciones de cuentas
