Descriptions

The affected product is vulnerable to an out-of-bounds read while processing project files, which allows an attacker to craft a project file that would allow arbitrary code execution.

El producto afectado es vulnerable a una lectura fuera de límites mientras son procesados archivos de proyecto, lo que permite a un atacante diseñar un archivo de proyecto que permita una ejecución de código arbitrario.

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 read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

*Credits: Khangkito of VinCSS and xina1i, working with Trend Micro’s Zero Day initiative, reported these vulnerabilities to CISA.
