Summary

CVE-2026-78308 is a critical Improper Authentication vulnerability (CWE-287) in Delta Electronics’ DIAEnergie industrial energy management software that allows an unauthenticated, remote attacker to bypass authentication entirely. The flaw affects all DIAEnergie versions prior to 1.11.00.022 and carries a CVSS v3.1 base score of 9.8 (Critical). It was disclosed alongside five other DIAEnergie vulnerabilities (CVE-2026-78309 through CVE-2026-78313) in a single Delta Product Cybersecurity Advisory.

Technical details

  • Root cause: DIAEnergie fails to properly enforce authentication controls on the affected functionality, classified under CWE-287 (Improper Authentication).
  • Trigger conditions: No authentication or user interaction is required to exploit the flaw; an attacker only needs network access to the exposed DIAEnergie application.
  • Attack vector: Network (AV:N) with low attack complexity (AC:L) and no privileges (PR:N) or user interaction (UI:N) required, per the published CVSS vector.
  • Impact: Successful exploitation results in a full authentication bypass, with high impact to confidentiality, integrity, and availability (C:H/I:H/A:H) — an attacker could gain unauthorized access to the industrial energy management platform, potentially allowing further compromise of monitored/controlled energy systems.

Affected software

  • Delta Electronics DIAEnergie — all versions prior to v1.11.00.022

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Contact Delta technical support to obtain and update to DIAEnergie v1.11.00.022 or later, which resolves the authentication bypass along with five other vulnerabilities disclosed in the same advisory.
  • If patching is not immediately possible:
    • Do not expose DIAEnergie or its underlying control systems and equipment directly to the internet.
    • Place DIAEnergie servers and related devices behind a firewall and isolate them from the general business network.
    • Require remote access to be performed only through a secure method such as a VPN.
    • Delta has stated no workaround exists for this vulnerability, so patching remains the only complete remediation.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
