Delta Electronics DOPSoft 2 Improper Input Validation Vulnerability
Delta Electronics - DOPSoft 2 · Listed in the CISA KEV since 2022-08-25. This indicates confirmed attacks in production environments.
Required action: The impacted product is end-of-life and should be disconnected if still in use.
CVE-2021-38406
HighCVSS 7.8KEVSummary
Delta Electronic DOPSoft 2 (Version 2.00.07 and prior) lacks proper validation of user-supplied data when parsing specific project files. This could result in multiple out-of-bounds write instances. An attacker could leverage this vulnerability to execute code in the context of the current process.
Risk Assessment
Enables arbitrary code execution on the engineering workstation, potentially compromising the industrial environment. High risk in OT/ICS environments.
Recommendation
Update DOPSoft 2 to a version later than 2.00.07. Open project files only from trusted sources and apply least privilege principles.
