Description

Delta Industrial Automation CNCSoft, CNCSoft ScreenEditor Version 1.00.88 and prior. Multiple stack-based buffer overflow vulnerabilities may be exploited by processing specially crafted project files, allowing an attacker to remotely execute arbitrary code. This may occur because CNCSoft lacks user input validation before copying data from project files onto the stack.

• CWE-121Stack-based Buffer OverflowA stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
• CWE-787Out-of-bounds WriteThe product writes data past the end, or before the beginning, of the intended buffer.
