Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
Delta Electronics DOPSoft 2 lacks proper validation of user-supplied data when parsing specific project files (improper input validation) resulting in an out-of-bounds write that allows for code execution.
CISA required action: The impacted product is end-of-life and should be disconnected if still in use.
