Descriptions

In Advantech DiagAnywhere Server, Versions 3.07.11 and prior, multiple stack-based buffer overflow vulnerabilities exist in the file transfer service listening on the TCP port. Successful exploitation could allow an unauthenticated attacker to execute arbitrary code with the privileges of the user running DiagAnywhere Server.

En Advantech DiagAnywhere Server, versiones 3.07.11 y anteriores, existen múltiples vulnerabilidades de desbordamiento de búfer en la región stack de la memoria en el servicio de transferencia de archivos que escucha sobre el puerto TCP. Una explotación con éxito podría permitir a un atacante no autenticado ejecutar código arbitrario con los privilegios del usuario que ejecuta DiagAnywhere Server.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech DiagAnywhere. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of FOLDER_REMOVE messages. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the server process.
