Descriptions

An issue was discovered on D-Link DIR-878 devices with firmware 1.12A1. This issue is a Command Injection allowing a remote attacker to execute arbitrary code, and get a root shell. A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted /HNAP1 POST request. This occurs when any HNAP API function triggers a call to the twsystem function with untrusted input from the request body for the SetSysEmailSettings API function, as demonstrated by shell metacharacters in the SMTPServerPort field.

Se ha descubierto un problema en dispositivos D-Link DIR-878 con firmware en su versión 1.12A1. Este problema es una inyección de comandos que permite que un atacante remoto ejecute código arbitrario y obtenga un shell root. Una vulnerabilidad de inyección de comandos permite que los atacantes ejecuten comandos arbitrarios del sistema operativo mediante una petición POST /HNAP1 manipulada. Esto ocurre cuando cualquier función API HNAP desencadena una llamada a la función twsystem con entradas no fiables del cuerpo de la petición para la función SetSysEmailSettings de la API, tal y como queda demostrado por metacaracteres shell en el campo SMTPServerPort.
