CVE-2026-79950: Dell Secure Connect Gateway Disclosure Flaw

CVE-2026-79950 is an information disclosure vulnerability in Dell Secure Connect Gateway caused by hard-coded credentials. Unauthenticated attackers can exploit this remotely to expose sensitive data. This article covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2026-79950 Overview

CVE-2026-79950 is a hard-coded credentials vulnerability [CWE-798] in Dell Secure Connect Gateway (SCG) 5.0. The flaw affects 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. An unauthenticated remote attacker can leverage embedded credentials to access protected functionality, resulting in information exposure. Dell published fixes in advisory DSA-2026-382.

Critical Impact
Unauthenticated network-based attackers can use embedded credentials to access sensitive information exposed by the Secure Connect Gateway service.

Affected Products

Dell Secure Connect Gateway 5.0 Appliance (Virtual Edition) prior to 5.36.00.16
Dell Secure Connect Gateway 5.0 Application prior to 5.36.00.00
Deployments exposing the SCG management or service interfaces to untrusted networks

Technical Details for CVE-2026-79950

Vulnerability Analysis

Dell Secure Connect Gateway (SCG) provides a remote support and telemetry channel between customer infrastructure and Dell backend services. The 5.0 release ships with hard-coded credentials embedded in the appliance or application. Because the credentials are static and shared across deployments, any attacker who recovers them can authenticate to affected instances without prior access.

The issue is reachable over the network without user interaction. Exploitation yields confidentiality impact only; integrity and availability of the appliance are not directly affected according to the CVSS vector. Recovered material may include configuration data, telemetry contents, or credentials handled by the gateway, all of which support downstream attacks against the connected Dell environment.

Root Cause

The root cause is the inclusion of static credentials inside the SCG appliance image and application distribution [CWE-798]. Hard-coded credentials cannot be rotated by administrators and are typically extractable through image analysis, firmware inspection, or documentation leakage. Every installation of the affected build shares the same secret, so a single disclosure compromises all unpatched instances.

Attack Vector

An unauthenticated attacker with network reachability to the SCG service authenticates using the embedded credentials. No privileges, user interaction, or social engineering are required. Once authenticated, the attacker queries interfaces that return sensitive information handled by the gateway. Internet-exposed or flat-network deployments are the highest-risk configurations.

No public proof-of-concept, exploit code, or CISA KEV listing is currently associated with this CVE. Technical specifics of the credentials and affected endpoints are not disclosed in Dell's advisory. See Dell Security Update DSA-2026-382 for vendor details.

Detection Methods for CVE-2026-79950

Indicators of Compromise

Authentication events on SCG management or API endpoints from source addresses outside the expected administrative subnet
Unexpected outbound data transfers or configuration exports from the SCG appliance
Presence of Dell SCG appliance images with build strings below 5.36.00.16 or application builds below 5.36.00.00

Detection Strategies

Inventory all Dell Secure Connect Gateway 5.0 deployments and compare running versions against the fixed builds in DSA-2026-382
Review web server, API, and SSH logs on SCG hosts for successful authentications that do not correlate with known administrator activity
Alert on SCG appliance network flows to destinations other than approved Dell endpoints and internal management subnets

Monitoring Recommendations

Forward SCG appliance logs and network telemetry to a centralized analytics platform for continuous review
Baseline normal administrative access patterns and flag deviations in source IP, time of day, and request volume
Monitor for new external scans probing SCG service ports following advisory publication

How to Mitigate CVE-2026-79950

Immediate Actions Required

Upgrade Dell SCG 5.0 Appliance to 5.36.00.16 or later and Dell SCG 5.0 Application to 5.36.00.00 or later
Restrict network access to SCG management interfaces to trusted administrative subnets only
Rotate any credentials, API tokens, or certificates that the SCG appliance handled prior to patching
Review historical SCG logs for authentication and data access anomalies during the exposure window

Patch Information

Dell has released fixed versions as documented in Dell Security Update DSA-2026-382. Apply the appliance update to versions at or above 5.36.00.16 and the application update to versions at or above 5.36.00.00. No configuration-only mitigation removes the embedded credentials; patching is required.

Workarounds

Place SCG appliances behind a firewall that permits inbound access only from designated administrative hosts
Segment SCG appliances onto a dedicated management VLAN with no direct internet exposure
Enforce egress filtering so SCG hosts can only reach documented Dell support endpoints

bash

# Example: restrict inbound access to the SCG management interface using iptables
iptables -A INPUT -p tcp --dport 443 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
iptables -A INPUT -p tcp --dport 22  -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 22  -j DROP
