CVE-2019-10947: Delta Industrial Automation CNCSoft ScreenEditor DPB File Parsing wMessageLen Stack-based Buffer Overflow Remote Code Execution Vulnerability
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.
Other sources
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 PanelName element, 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 the Administrator.
