Descriptions

Apache log4net versions before 2.0.10 do not disable XML external entities when parsing log4net configuration files. This allows for XXE-based attacks in applications that accept attacker-controlled log4net configuration files.

Apache log4net versiones anteriores a 2.0.10, no deshabilita las entidades externas XML cuando analiza los archivos de configuración de log4net. Esto permite realizar ataques basados en XXE en aplicaciones que aceptan archivos de configuración log4net controlados por el atacante

It was discovered that Apache Log4net incorrectly handled certain configuration files. An attacker could possibly use this issue to expose sensitive information.
