Summary

CVE-2026-80132 is a Missing Authentication for Critical Function vulnerability (CWE-306) affecting Dell Secure Connect Gateway (SCG) 5.0. The flaw allows an unauthenticated attacker with network access to potentially gain unauthorized access to the system. Dell rates this vulnerability High severity with a CVSS v3.1 base score of 8.1.

Technical details

  • Root cause: a critical function within Dell SCG 5.0 lacks proper authentication controls (CWE-306).
  • Trigger conditions: no attacker credentials are required; the flaw is reachable by any actor with remote network access to the exposed SCG interface.
  • Attack vector: Network (AV:N), with high attack complexity (AC:H) and no privileges (PR:N) or user interaction (UI:N) required.
  • Impact: successful exploitation can lead to high impact on confidentiality, integrity, and availability, potentially granting unauthorized system access.

Affected software

  • Dell Secure Connect Gateway 5.0 – Application: versions prior to 5.36.00.00
  • Dell Secure Connect Gateway 5.0 – Appliance: versions prior to 5.36.00.16

Severity

  • CVSS v3.1 Base Score: 8.1 (High)
  • Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade Dell Secure Connect Gateway 5.0 Application to version 5.36.00.00 or later.
  • Immediate: Upgrade Dell Secure Connect Gateway 5.0 Appliance to version 5.36.00.16 or later.
  • If patching cannot be performed immediately, restrict network access to the SCG management interface to trusted hosts/VPN only, and monitor for anomalous unauthenticated access attempts until the update can be applied.

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.
