Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Improper Certificate Validation vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to unauthorized access.
AnalysisAI
Improper certificate validation in Dell Secure Connect Gateway (SCG) 5.0 - both Appliance (prior to 5.36.00.16) and Application/Virtual Edition (prior to 5.36.00.00) - allows an unauthenticated remote attacker with a network man-in-the-middle position to intercept or tamper with TLS-protected communications between the SCG and remote endpoints. The CVSS 5.6 score with AC:H reflects that exploitation is constrained by the requirement for network-level interception capability rather than direct remote access. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to achieve a network-level man-in-the-middle position between the Dell SCG deployment and the remote endpoint (e.g., Dell support infrastructure or a backend service the SCG communicates with). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.6 base score with AC:H accurately reflects a moderate-priority vulnerability constrained by the MITM prerequisite, limiting opportunistic internet-scale exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patches are available per DSA-2026-382. … Detailed patch versions, workarounds, and compensating controls in full report. |
