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 5.0 (both Appliance and Application variants) enables an unauthenticated remote attacker with a man-in-the-middle network position to intercept and modify encrypted communications between the SCG platform and Dell's support infrastructure. Rated CVSS 7.4 (CWE-295) with high confidentiality and integrity impact, this flaw is particularly sensitive given that SCG routinely carries privileged support telemetry and credentials. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must establish a man-in-the-middle position on the network path between the Dell SCG instance and Dell's external support infrastructure - this is the principal limiting constraint reflected in CVSS AC:H, and excludes purely passive or remote attackers lacking network positioning. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.4 vector (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) accurately characterizes the threat profile: network-reachable and requiring no authentication or user interaction, but constrained by the need for attacker-controlled network positioning (AC:H). … 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 patch: upgrade Dell SCG 5.0 Appliance to version 5.36.00.16 or later and Dell SCG 5.0 Application to version 5.36.00.00 or later per Dell advisory DSA-2026-382 (https://www.dell.com/support/kbdoc/en-in/000503426/dsa-2026-382-security-update-for-dell-secure-connect-gateway-virtual-edition-multiple-vulnerabilities). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all Dell SCG 5.0 instances in your environment (both Appliance and Application variants) and assess which are exposed to potential man-in-the-middle attack positions. …
