Descriptions

In pfSense 2.4.4_1, blocking of source IP addresses on the basis of failed HTTPS authentication is inconsistent with blocking of source IP addresses on the basis of failed SSH authentication (the behavior does not match the sshguard documentation), which might make it easier for attackers to bypass intended access restrictions.

En pfSense 2.4.4_1, el bloqueo de las direcciones IP de origen al haber un error de autenticación HTTPS es inconsistente con el bloqueo de direcciones IP de origen al haber un error de autenticación SSH (este comportamiento no coincide con la documentación de sshguard). Esto podría facilitar que los atacantes omitan las restricciones de acceso planeadas.
