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 Handling of Highly Compressed Data (Data Amplification) vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to denial of service.
AnalysisAI
Denial-of-service via compression bomb in Dell Secure Connect Gateway (SCG) 5.0 allows unauthenticated remote attackers to exhaust server resources by sending highly compressed payloads that expand dramatically upon decompression. Both the Appliance variant (prior to 5.36.00.16) and the Application variant (prior to 5.36.00.00) are affected. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires unauthenticated network access to a reachable Dell SCG 5.0 service endpoint - no credentials, prior authentication, or user interaction are needed, consistent with the CVSS AV:N/AC:L/PR:N/UI:N vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) 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 Secure Connect Gateway 5.0 Appliance to version 5.36.00.16 or later, and Dell Secure Connect Gateway 5.0 Application to version 5.36.00.00 or later, per DSA-2026-382 (https://www.dell.com/support/kbdoc/en-in/000503426/dsa-2026-382-security-update-for-dell-secure-connect-gateway-virtual-edition-multiple-vulnerabilities). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Dell SCG deployments across Appliance (versions prior to 5.36.00.16) and Application (versions prior to 5.36.00.00) variants and identify systems at highest risk based on network exposure and user criticality. …
