CVE-2026-80057 Overview
CVE-2026-80057 affects Dell Secure Connect Gateway (SCG) 5.0 Appliance and Application editions. The vulnerability stems from the use of a hard-coded cryptographic key [CWE-321] within the product. A low-privileged attacker with local access to the appliance can exploit the embedded key material to disclose sensitive information. Dell addressed the issue in Appliance version 5.36.00.16 and Application version 5.36.00.00. The flaw affects confidentiality only and does not impact system integrity or availability.
Critical Impact
A local, low-privileged attacker can leverage the hard-coded cryptographic key to decrypt or access protected data handled by Dell SCG, resulting in information disclosure.
Affected Products
- Dell Secure Connect Gateway 5.0 Appliance versions prior to 5.36.00.16
- Dell Secure Connect Gateway 5.0 Application versions prior to 5.36.00.00
- Dell Secure Connect Gateway Virtual Edition (per DSA-2026-382 advisory scope)

Technical Details for CVE-2026-80057
Vulnerability Analysis
Dell SCG ships with a cryptographic key embedded directly in the product. Because the key is identical across deployments, any actor who obtains it can decrypt protected data across every affected installation. The vulnerability is exploitable only from a local context and requires low privileges, but it does not require user interaction. Successful exploitation yields high confidentiality impact without altering integrity or availability. Dell distributes the corrective fix through security advisory DSA-2026-382.
Root Cause
The root cause is the storage of a static, hard-coded cryptographic key within the SCG binaries or configuration, classified under [CWE-321]. Cryptographic protections that depend on secrets embedded in shipped software collapse once the secret is extracted. Attackers can recover the key through binary analysis, filesystem inspection, or memory examination on any affected appliance and reuse it against other Dell SCG deployments protecting equivalent data.
Attack Vector
Exploitation requires local access with low privileges on the SCG appliance or its host environment. An attacker with a valid low-privileged shell or file-system read access enumerates SCG components, extracts the hard-coded key, and applies it to decrypt configuration, credential, or telemetry data protected by the key. No user interaction is required. Because the key is shared across installations, an attacker who extracts it from a lab appliance can reuse it against production instances they can access locally.
No public proof-of-concept exploit is available. See the Dell Security Update DSA-2026-382 advisory for vendor-provided technical context.
Detection Methods for CVE-2026-80057
Indicators of Compromise
- Unauthorized local shell sessions or interactive logins on SCG appliances by low-privileged accounts
- Unexpected read access to SCG binaries, configuration files, or key material by non-administrative users
- Anomalous process execution invoking cryptographic libraries or extracting embedded resources from SCG components
Detection Strategies
- Inventory all Dell SCG 5.0 Appliance and Application instances and compare installed versions against the fixed builds 5.36.00.16 and 5.36.00.00.
- Baseline expected local users and processes on SCG hosts; alert on deviations that touch SCG installation directories.
- Correlate file-access telemetry on SCG configuration and key stores with authenticated user identity to surface unauthorized reads.
Monitoring Recommendations
- Forward SCG operating system audit logs, authentication events, and file integrity monitoring data to a centralized analytics platform.
- Monitor for privilege changes, new local account creation, and lateral movement toward SCG hosts from adjacent systems.
- Track outbound data flows from SCG appliances for unusual volumes or destinations that may indicate exfiltration of decrypted data.
How to Mitigate CVE-2026-80057
Immediate Actions Required
- Upgrade Dell SCG 5.0 Appliance to version 5.36.00.16 or later and Dell SCG 5.0 Application to 5.36.00.00 or later per DSA-2026-382.
- Restrict local and interactive access to SCG appliances to a minimal set of administrative users.
- Rotate any credentials, tokens, or secrets that were stored or processed by an unpatched SCG instance.
Patch Information
Dell published fixed releases in security advisory Dell Security Update DSA-2026-382. Apply the vendor-supplied update for Secure Connect Gateway Virtual Edition to remediate the hard-coded key and associated vulnerabilities addressed in the same advisory.
Workarounds
- Enforce network segmentation so SCG appliances reside in a restricted management zone accessible only to authorized administrators.
- Enable file integrity monitoring on SCG installation directories and configuration stores to detect tampering or unauthorized reads.
- Review and prune local accounts on SCG hosts, removing shell access for accounts that do not require it.
# Verify installed Dell SCG version against fixed release
rpm -qa | grep -i secure-connect-gateway
# Expected: version >= 5.36.00.16 (Appliance) or >= 5.36.00.00 (Application)
# Restrict local shell access to SCG administrators only
sudo chmod 700 /opt/dell/secureconnectgateway
sudo chown -R scgadmin:scgadmin /opt/dell/secureconnectgateway
