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 protection mechanism bypass.
AnalysisAI
Improper certificate validation in Dell Secure Connect Gateway (SCG) 5.0 enables a network-positioned unauthenticated attacker to intercept encrypted communications via a man-in-the-middle attack, bypassing TLS-based trust mechanisms. Both the appliance form factor (versions prior to 5.36.00.16) and the virtual/application form factor (versions prior to 5.36.00.00) are affected. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to achieve a network man-in-the-middle position on the path between the Dell SCG appliance or application instance and the remote endpoint it communicates with - this is the source of AC:H in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 5.9 (Medium) with vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N reflects a realistic middle-ground assessment. … 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: SCG 5.0 Appliance 5.36.00.16 and SCG 5.0 Application 5.36.00.00. … Detailed patch versions, workarounds, and compensating controls in full report. |
