Descriptions

CNCSoft Version 1.00.83 and prior with ScreenEditor Version 1.00.54 has multiple stack-based buffer overflow vulnerabilities that could cause the software to crash due to lacking user input validation before copying data from project files onto the stack. Which may allow an attacker to gain remote code execution with administrator privileges if exploited.

CNCSoft en versiones 1.00.83 y anteriores con ScreenEditor 1.00.54 tiene múltiples vulnerabilidades de desbordamiento de búfer basado en pila que podría provocar el cierre inesperado del software debido a la falta de validación de entradas de usuario antes de copiar los datos del los archivos de proyecto a la pila. Esto puede permitir a un atacante ejecutar código remotamente con privilegios de administrador si se explota.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Delta Industrial Automation CNCSoft ScreenEditor. 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 handling of DPB files. When parsing the wKPFString attribute, the process does not properly validate 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 Administrator.
