Descriptions

Delta Industrial Automation CNCSoft, CNCSoft ScreenEditor Version 1.00.88 and prior. Multiple heap-based buffer overflow vulnerabilities may be exploited by processing specially crafted project files, allowing an attacker to remotely execute arbitrary code. There is a lack of user input validation before copying data from project files onto the heap.

Delta Industrial Automation CNCSoft, CNCSoft ScreenEditor versión 1.00.88 y anteriores. Se pueden aprovechar múltiples vulnerabilidades de desbordamiento de búfer en la región heap de la memoria, mediante el procesamiento de archivos de proyecto especialmente creados, lo que permite a un atacante ejecutar código arbitrario de forma remota. Falta una comprobación de entrada del usuario antes de copiar los datos de los archivos del proyecto en la pila.

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 parsing of DPB files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the Administrator.
