Descriptions

FATEK FvDesigner version 1.5.103 and prior is vulnerable to an out-of-bounds write while processing project files. If a valid user is tricked into using maliciously crafted project files, an attacker could achieve arbitrary code execution.

FATEK FvDesigner versión 1.5.103 y anteriores, es vulnerable a una escritura fuera de límites mientras son procesados archivos de proyecto. Si es engañado a un usuario válido para que use archivos de proyecto mal diseñados, un atacante podría lograr 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 write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.

*Credits: Anonymous, working with Trend Micro’s Zero Day Initiative, reported this vulnerability to CISA.
