This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-2150 routers. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the SOAP API interface, which listens on TCP port 80 by default. A crafted authentication header can cause authentication to succeed without providing proper credentials. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-20910."

Esta vulnerabilidad permite a atacantes adyacentes a la red eludir la autenticaci\u00f3n en las instalaciones afectadas de los enrutadores D-Link DIR-2150. No se requiere autenticaci\u00f3n para aprovechar esta vulnerabilidad. La falla espec\u00edfica existe dentro de la interfaz API SOAP, que escucha en el puerto TCP 80 de forma predeterminada. Un encabezado de autenticaci\u00f3n manipulado puede hacer que la autenticaci\u00f3n se realice correctamente sin proporcionar las credenciales adecuadas. Un atacante puede aprovechar esta vulnerabilidad para eludir la autenticaci\u00f3n en el sistema. Era ZDI-CAN-20910."
