Lifecycle Timeline
3DescriptionCVE.org
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 exposes both Appliance and Application deployments to unauthenticated remote exploitation, enabling MITM-style attacks that bypass TLS trust enforcement and grant unauthorized access to communications relayed through the gateway. The Appliance variant is affected below version 5.36.00.16 and the Application variant below 5.36.00.00. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to occupy a network path capable of intercepting or spoofing TLS connections initiated by the Dell SCG instance - achievable via ARP poisoning on a shared LAN, DNS hijacking, or rogue routing. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) reflects an unauthenticated, network-exploitable flaw with balanced low-moderate impact across confidentiality, integrity, and availability. … 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 | Upgrade Dell Secure Connect Gateway 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, as directed by Dell advisory DSA-2026-382 at 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, inventory all Dell Secure Connect Gateway deployments (Appliance below version 5.36.00.16 and Application below version 5.36.00.00), identify which are internet-reachable, and immediately restrict network access to trusted networks only. …
