They should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.

Why it matters

CVE-2026-80238 is a critical vulnerability in Dell Secure Connect Gateway 5.0 Appliance and Application that allows an unauthenticated attacker with local access to potentially exploit the vulnerability, leading to protection mechanism bypass. System administrators and security teams responsible for Dell Secure Connect Gateway 5.0 Appliance and Application deployments should assess exposure and prioritize remediation due to the critical severity of this vulnerability.

• Potential for protection mechanism bypass
• Possible escalation of privileges
• Risk of unauthorized access to sensitive data
• Need for urgent remediation due to critical severity

Technical summary

The vulnerability is due to an exposed Docker socket, which allows an attacker to gain root-level access to the host without requiring a password. This vulnerability is considered critical because a low-privileged operator with SSH access to the SCG host can gain root-level access to the host without requiring a password by leveraging the exposed Docker socket. An attacker who compromises a service running within the orchestrator container can access the same socket and escape the container boundary to obtain host-level control.

Defensive priority

Upgrade to the latest version as recommended by Dell

Recommended defensive actions

• Upgrade Dell SCG 5.0 Appliance to version 5.36.00.16 or later
• Upgrade Dell SCG 5.0 Application to version 5.36.00.00 or later
• Restrict SSH access to the SCG host
• Monitor for suspicious activity on the SCG host
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes
