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 exposes both Appliance and Application variants to protection mechanism bypass by unauthenticated remote attackers. The flaw (CWE-295) allows an adversary in a network-interception position to present an invalid or attacker-controlled TLS certificate that the SCG accepts without proper verification, potentially enabling interception or manipulation of communications between the gateway and backend or managed systems. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to achieve a man-in-the-middle network position between the Dell SCG instance and its TLS communication peer - for example, via ARP spoofing on the same network segment, DNS cache poisoning, or BGP route manipulation to redirect outbound SCG connections. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS 7.3 with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L treats this as low-complexity, unauthenticated network exploitation - but this warrants scrutiny. … 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 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 at https://www.dell.com/support/kbdoc/en-in/000503426/. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
