CVE-2026-80056 Overview
CVE-2026-80056 is an information disclosure vulnerability affecting Dell Secure Connect Gateway (SCG) 5.0. The flaw stems from the insertion of sensitive information into log files [CWE-532]. A low-privileged attacker with local access to the appliance can read log content that exposes sensitive data. Dell tracks this issue under advisory DSA-2026-382 and has released fixed versions for both the appliance and application distributions.
Critical Impact
A local, authenticated attacker with low privileges can retrieve sensitive information written to log files, enabling further reconnaissance or credential reuse against the Secure Connect Gateway environment.
Affected Products
- Dell SCG 5.0 Appliance versions prior to 5.36.00.16
- Dell SCG 5.0 Application versions prior to 5.36.00.00
- Dell Secure Connect Gateway Virtual Edition

Technical Details for CVE-2026-80056
Vulnerability Analysis
Dell Secure Connect Gateway provides a communication channel between customer environments and Dell support services. The affected versions write sensitive information into log files that are readable in the context of a local, low-privileged account. An attacker who has already obtained interactive or shell access to the appliance can harvest this data without triggering privileged operations.
The exposure is limited to confidentiality; the attacker cannot alter data or disrupt service through this flaw alone. However, the data recovered from logs can accelerate lateral movement or provide credentials, tokens, or configuration details that support subsequent attacks against connected Dell infrastructure.
Root Cause
The root cause is improper handling of sensitive data during logging, categorized as CWE-532: Insertion of Sensitive Information into Log File. The affected components fail to redact or omit sensitive fields before they are persisted to log storage, leaving the information available to any principal with read access to those files.
Attack Vector
Exploitation requires local access to the SCG appliance or application host and low-level privileges. No user interaction is needed. The attacker enumerates log directories used by the Secure Connect Gateway service and reads records that contain sensitive fields. Refer to the Dell Security Update DSA-2026-382 advisory for vendor-specific technical detail.
Detection Methods for CVE-2026-80056
Indicators of Compromise
- Unexpected read access to Secure Connect Gateway log directories by non-administrative local accounts.
- Copy, archive, or exfiltration operations targeting SCG log files by processes outside the normal logging pipeline.
- Shell sessions on the SCG appliance from service accounts that historically do not perform interactive logins.
Detection Strategies
- Audit file access events on SCG log directories and alert on reads by principals other than the logging daemon or approved administrators.
- Correlate local logon activity on the SCG host with subsequent access to log or backup directories.
- Review privileged access management logs to identify low-privileged accounts that gained interactive access to the appliance.
Monitoring Recommendations
- Enable filesystem auditing on Secure Connect Gateway log paths and forward events to a centralized log platform.
- Baseline expected processes that read SCG log files and alert on deviations.
- Track upgrade status of SCG appliance and application instances against the fixed versions listed in DSA-2026-382.
How to Mitigate CVE-2026-80056
Immediate Actions Required
- Upgrade Dell SCG 5.0 Appliance to version 5.36.00.16 or later.
- Upgrade Dell SCG 5.0 Application to version 5.36.00.00 or later.
- Review existing log files on affected instances and rotate any credentials, tokens, or secrets that may have been recorded.
- Restrict local and interactive access to the SCG host to a minimum set of administrative accounts.
Patch Information
Dell has published fixed builds through advisory DSA-2026-382. Apply the updated appliance image or application package to remediate CVE-2026-80056. After patching, rotate any secrets that may have been exposed in prior log data and purge historical log files that predate the fix.
Workarounds
- Tighten filesystem permissions on SCG log directories so only the logging service and administrators can read them.
- Remove or archive historical log files to offline storage protected by stricter access controls until patching is complete.
- Limit which local accounts can authenticate to the SCG host, and disable unused service or maintenance accounts.
# Configuration example
# Restrict read access on SCG log directories to root and the logging group
chown -R root:scglog /var/log/scg
chmod -R o-rwx,g-w /var/log/scg
