Halo Surface Signal score for CVE-2025-62582

Delta Electronics DIAView is SCADA/HMI software used for industrial automation. While these systems are typically deployed within internal OT or ICS networks and protected by firewalls, they are sometimes exposed to the internet or accessible via remote gateways in specific industrial monitoring configurations, making reachability possible but not a standard or intended public-facing design.

PCI scan relevance

PCI Relevance for CVE-2025-62582

Yes

CVE-2025-62582 — Halo PCI Relevance: Yes. Under typical PCI ASV external scan criteria, this issue may be flagged for scan prioritization.

This vulnerability involves missing authentication for a critical function, which is an automatic-fail class for PCI ASV scans. The critical severity (base score 9.8) and network-accessible attack vector indicate a high risk of compromise.

Scan-prioritization guidance only—not a PCI DSS certification or ASV attestation.

Horizon Alert
