AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
MITM via cert bypass enables both reading (C:H) and injecting (I:L) TLS-protected traffic; AC:H because network interception position is required.

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 protection mechanism bypass.
AnalysisAI
Improper certificate validation in Dell Secure Connect Gateway (SCG) 5.0 allows a remote, network-positioned attacker to intercept TLS-protected communications via a man-in-the-middle attack, bypassing the TLS protection mechanism and exposing high-confidentiality data. Both the Appliance form factor (versions prior to 5.36.00.16) and the Application form factor (versions prior to 5.36.00.00) are affected. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to establish a network man-in-the-middle position between the Dell SCG instance and its remote communication target - this is a non-default, non-trivial prerequisite (reflected in CVSS AC:H). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 score of 5.9 (Medium) with vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N accurately reflects the real-world attack bar. … 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 Application to version 5.36.00.00 or later and Dell Secure Connect Gateway 5.0 Appliance to version 5.36.00.16 or later, as directed by Dell advisory DSA-2026-382 (https://www.dell.com/support/kbdoc/en-in/000503426). … Detailed patch versions, workarounds, and compensating controls in full report. |
