Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H
AC:H because certificate forgery for MITM or bypass typically requires network positioning; C:L added because 'unauthorized access' implies some data exposure, contradicting vendor's C:N.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No authentication is required per the CVSS PR:N vector - the vulnerability is reachable by any remote attacker with network connectivity to the SCG service port. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-provided CVSS 8.2 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H) presents a notable internal inconsistency: C:N (no confidentiality impact) conflicts with the description's claim of 'unauthorized access,' which typically implies at minimum some confidentiality exposure. … 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 | Dell has released fixes in DSA-2026-382: upgrade Dell SCG 5.0 Appliance (Virtual Edition) to version 5.36.00.16 or later, and upgrade Dell SCG 5.0 Application to version 5.36.00.00 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
