TITLE
Fatek Automation FvDesigner FPJ File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
Trust: 0.7
DESCRIPTION
Fatek FvDesigner Version 1.5.76 and prior is vulnerable to a stack-based buffer overflow while project files are being processed, allowing an attacker to craft a special project file that may permit arbitrary code execution. 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 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 current process. Fatek FvDesigner is a software tool for designing and developing FATEK FV HMI series product projects
