Delta Industrial Automation CNCSoft ScreenEditor DPB File UserAlarm wMessage Stack-based Buffer Overflow Remote Code Execution Vulnerability

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 UserAlarm wMessage 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 under the context of Administrator.
