Summary

CVE-2025-62582 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Deltaww Diaview. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 6.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

AC-14 directly mitigates CWE-306 by requiring organizations to identify, authorize, and limit critical functions accessible without identification or authentication, preventing unauthenticated remote exploitation in CVE-2025-62582.

IA-8 Identification and Authentication (Non-organizational Users) good match

prevent

IA-8 mandates unique identification and authentication for non-organizational users, blocking the unauthenticated network access that enables high-impact compromise in this CVE.

AC-3 Access Enforcement good match

prevent

AC-3 enforces approved access authorizations including authentication requirements, ensuring critical DIAView functions are protected against unauthorized logical access.
