Lifecycle Timeline
2DescriptionCVE.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 Validation of Certificate with Host Mismatch vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to protection mechanism bypass.
AnalysisAI
Certificate hostname validation bypass in Dell Secure Connect Gateway (SCG) 5.0 enables unauthenticated remote attackers positioned on the network path to perform man-in-the-middle attacks against TLS-protected communications. The flaw (CWE-297) means SCG accepts certificates whose hostname does not match the server being contacted, allowing an adversary to impersonate backend endpoints and intercept or manipulate encrypted traffic. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to occupy a man-in-the-middle position on the network path between the Dell SCG 5.0 instance and the remote TLS endpoint it is connecting to - for example, via ARP spoofing on a local segment, a compromised upstream router, or BGP route manipulation for internet-facing deployments. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N) reflects a moderate real-world risk profile. … 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 patched builds addressing this vulnerability: upgrade the SCG 5.0 Appliance to version 5.36.00.16 or later, and the SCG 5.0 Application to version 5.36.00.00 or later, per advisory DSA-2026-382 (https://www.dell.com/support/kbdoc/en-in/000503426/). … Detailed patch versions, workarounds, and compensating controls in full report. |
