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 unauthorized access.
AnalysisAI
Improper certificate validation in Dell Secure Connect Gateway 5.0 (both Appliance and Application editions) exposes encrypted communications to interception by remote, unauthenticated attackers positioned on the network path. The vulnerability stems from CWE-295 failure to properly verify TLS/SSL certificates, enabling a MITM attacker to present a fraudulent certificate that the product accepts, thereby gaining access to traffic that should be protected. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be positioned on the network path between the vulnerable SCG appliance/application and Dell's support backend - achievable via ARP spoofing on the same local network segment, rogue gateway injection, or BGP-level route hijacking for internet-routed traffic. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is moderate. … 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 Appliance to version 5.36.00.16 or later, and Dell SCG 5.0 Application to version 5.36.00.00 or later, as directed in Dell Security Advisory DSA-2026-382 at https://www.dell.com/support/kbdoc/en-in/000503426. … Detailed patch versions, workarounds, and compensating controls in full report. |
