Title
GeoVision GV-VMS V20 WebCam Server Login stack overflow vulnerability
Summary
A stack overflow vulnerability exists in the WebCam Server Login functionality of GeoVision GV-VMS V20 20.0.2. A specially crafted HTTP request can lead to an arbitrary code execution. An attacker can make an unauthenticated HTTP request to trigger this vulnerability. #### Stack-overflow via unconstrained sscanf The call to `sscanf` at [1] to split the `Buffer` variable into the `username` and `password` variables doesn't limit the size of the extracted content to match the destination buffers' sizes. In this case, if either the username or password decoded from the authorization string exceeds `40` characters (the size the stack variables `username` and `password`) then a stack overflow will occur. The data is controlled by an attacker, but sronger constraints (e.g. no null bytes) may make exploitation harder. A successful attack could lead to full code execution as SYSTEM on the machine running the service.

Una solicitud HTTP especialmente dise\u00f1ada puede conducir a una ejecuci\u00f3n de c\u00f3digo arbitrario. Un atacante puede realizar una solicitud HTTP no autenticada para activar esta vulnerabilidad.\n\n#### Desbordamiento de pila a trav\u00e9s de sscanf sin restricciones\n\nLa llamada a \u201csscanf\u201d en [1] para dividir la variable \u201cBuffer\u201d en las variables \u201cusername\u201d y \u201cpassword\u201d no limita el tama\u00f1o del contenido extra\u00eddo para que coincida con los tama\u00f1os de los b\u00faferes de destino. En este caso, si el nombre de usuario o la contrase\u00f1a decodificados de la cadena de autorizaci\u00f3n excede los \u201c40\u201d caracteres (el tama\u00f1o de las variables de pila \u201cusername\u201d y \u201cpassword\u201d), entonces ocurrir\u00e1 un desbordamiento de pila.\n\nLos datos son controlados por un atacante, pero restricciones m\u00e1s fuertes (por ejemplo, sin bytes nulos) pueden dificultar la explotaci\u00f3n. Un ataque exitoso podr\u00eda conducir a la ejecuci\u00f3n completa de c\u00f3digo como SYSTEM en la m\u00e1quina que ejecuta el servicio."
