Descriptions

Fatek FvDesigner Version 1.5.76 and prior is vulnerable to an out-of-bounds write while processing project files, allowing an attacker to craft a special project file that may permit arbitrary code execution.

Fatek FvDesigner versiones 1.5.76 y anteriores, es vulnerable a una escritura fuera de límites mientras procesa archivos de proyecto, lo que permite a un atacante diseñar un archivo de proyecto especial que puede permitir una ejecución de código arbitraria

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fatek Automation FvDesigner. 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 parsing of FPJ 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.
