Summary
An issue was discovered in HCC embedded InterNiche 4.0.1. A potential heap buffer overflow exists in the code that parses the HTTP POST request, due to lack of size validation. This vulnerability requires the attacker to send a crafted HTTP POST request with a URI longer than 50 bytes. This leads to a heap overflow in wbs_post() via an strcpy() call.

Se presenta un potencial desbordamiento del b\u00fafer de la pila en el c\u00f3digo que analiza la petici\u00f3n HTTP POST, debido a una falta de comprobaci\u00f3n del tama\u00f1o. Esta vulnerabilidad requiere que el atacante env\u00ede una petici\u00f3n HTTP POST dise\u00f1ada con un URI de m\u00e1s de 50 bytes. Esto conlleva a un desbordamiento de pila en la funci\u00f3n wbs_post() por medio de una llamada a la funci\u00f3n strcpy()."
