Descriptions

In Advantech WebAccess HMI Designer Version 2.1.9.23 and prior, processing specially crafted MCR files lacking proper validation of user supplied data may cause the system to write outside the intended buffer area, allowing remote code execution.

En WebAccess HMI Designer de Advantech versión 2.1.9.23 y anteriores, el procesamiento de archivos MCR especialmente diseñados que carecen de una comprobación apropiada de datos suministrados por el usuario, puede causar que el sistema escriba fuera del área de búfer prevista, permitiendo la ejecución de código remota.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess HMI Designer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the processing of MCR files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
