This will allow an attacker to send a NEWSCAN request to a listening agent on the network as well as receive the agent's HTTP request verifying its authtoken. In AEAgent.cpp, the agent responding back over HTTP is vulnerable to a Heap Overflow if the POST payload response is too large. The POST payload response is converted to Unicode using vswprintf. This is written to a buffer only 0x2000 bytes big. If POST payload is larger, then heap overflow will occur."},{"lang":"es","value":"Debido a que el agente de Asset Explorer no comprueba los certificados HTTPS, un atacante en la red puede configurar estáticamente su dirección IP para que coincida con la dirección IP del servidor de Asset Explorer. Esto permitirá a un atacante enviar una petición NEWSCAN a un agente que esté escuchando en la red, así como recibir la petición HTTP del agente comprobando su authtoken. En el archivo AEAgent.cpp, el agente que responde a través de HTTP es vulnerable a un Desbordamiento de Pila si la respuesta de la carga útil POST es demasiado grande. La respuesta de la carga útil POST se convierte a Unicode usando vswprintf. Esto se escribe en un buffer de sólo 0x2000 bytes de tamaño.
