Delta Electronics DOPSoft 2 Improper Input Validation Vulnerability — 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. Listed in the CISA KEV catalog (added 2022-08-25) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~78%. Treat it as real and prioritize remediation over triage.
- 0
Required action for Delta Electronics DOPSoft 2: The impacted product is end-of-life and should be disconnected if still in use. CISA set a federal remediation due date of 2022-09-15. After patching, verify the vulnerable path is no longer reachable before closing the finding.
