Descriptions

The Blackhole for Bad Bots WordPress plugin before 3.3.2 uses headers such as CF-CONNECTING-IP, CLIENT-IP etc to determine the IP address of requests hitting the blackhole URL, which allows them to be spoofed. This could result in blocking arbitrary IP addresses, such as legitimate/good search engine crawlers / bots. This could also be abused by competitors to cause damage related to visibility in search engines, can be used to bypass arbitrary blocks caused by this plugin, block any visitor or even the administrator and even more.

El plugin Blackhole for Bad Bots de WordPress versiones anteriores a 3.3.2, usa encabezados como CF-CONNECTING-IP, CLIENT-IP, etc. para determinar la dirección IP de las peticiones que llegan a la URL del blackhole, lo que permite que sean suplantadas. Esto podría resultar en el bloqueo de direcciones IP arbitrarias, tales como rastreadores / bots de motores de búsqueda legítimos / buenos. Esto también podría ser abusado por los competidores para causar daños relacionados con la visibilidad en los motores de búsqueda, puede ser usado para omitir los bloqueos arbitrarios causados por este plugin, bloquear cualquier visitante o incluso el administrador y aún más
