CVE-2026-80177: Dell Secure Connect Gateway SQL Injection

CVE-2026-80177 Overview

CVE-2026-80177 is an SQL Injection vulnerability [CWE-89] affecting Dell Secure Connect Gateway (SCG) 5.0. The flaw stems from improper neutralization of special elements used in an SQL command. A low-privileged attacker with remote access can exploit the vulnerability to inject SQL and script content into the application. The issue affects both the SCG 5.0 Appliance and the SCG 5.0 Application distributions.

Critical Impact
An authenticated remote attacker with low privileges can inject SQL statements, leading to script injection and confidentiality impact on the Dell Secure Connect Gateway backend.

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

Technical Details for CVE-2026-80177

Vulnerability Analysis

The vulnerability is an SQL Injection weakness in Dell Secure Connect Gateway, a remote support and telemetry gateway deployed to relay device data to Dell backend services. The affected component fails to neutralize special SQL syntax characters in user-supplied input before incorporating that input into database queries. Because SCG exposes web management interfaces to authenticated operators, a low-privileged account is sufficient to reach the vulnerable code path.

Exploitation produces confidentiality impact on the underlying database. Dell's advisory also notes the vulnerability can lead to script injection, meaning attacker-controlled content may be stored and later rendered to other users of the management interface. The vulnerability does not require user interaction.

Root Cause

The root cause is improper neutralization of special elements in an SQL command [CWE-89]. Input received from an authenticated user is concatenated or interpolated into an SQL statement without parameterization or sufficient input validation. This allows the attacker to alter query structure and inject additional SQL clauses or payloads that are later reflected as script content.

Attack Vector

The attack vector is network-based and requires low privileges with no user interaction. An attacker authenticates to the SCG management interface, then submits crafted input containing SQL metacharacters to a vulnerable parameter. The database processes the injected statement, returning sensitive data or persisting attacker-controlled strings that are later rendered as scripts in the web UI. No verified proof-of-concept is publicly available at the time of publication.

Detection Methods for CVE-2026-80177

Indicators of Compromise

Unexpected SQL syntax characters (single quotes, UNION, --, ;) in HTTP request parameters submitted to SCG management endpoints.
Application or database error messages logged by SCG referencing malformed SQL statements.
Persisted fields in the SCG UI that render unexpected <script> tags or HTML markup to other authenticated users.
Authenticated sessions from low-privileged accounts generating anomalous database query volumes.

Detection Strategies

Inspect SCG web server and application logs for POST or GET parameters containing SQL keywords originating from non-administrator accounts.
Deploy web application firewall signatures tuned for SQL injection patterns against the SCG management interface hostname.
Correlate authentication events with subsequent database error events on the SCG appliance to surface injection attempts.

Monitoring Recommendations

Forward SCG appliance logs to a centralized SIEM and alert on repeated SQL error patterns from a single session.
Monitor for outbound data flows from SCG that exceed baseline volumes, which may indicate database exfiltration.
Track privileged and low-privileged account activity within SCG and alert on unusual configuration or query behavior.

How to Mitigate CVE-2026-80177

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.
Audit SCG user accounts and remove or disable any unnecessary low-privileged operator accounts.
Restrict network access to the SCG management interface to trusted administrative networks only.

Patch Information

Dell has released fixed builds in advisory DSA-2026-382. Administrators should install the vendor-supplied update by following the instructions in the Dell Security Update DSA-2026-382 advisory. The fixed versions are 5.36.00.16 for the Appliance and 5.36.00.00 for the Application.

Workarounds

Place the SCG management interface behind a network segmentation boundary and permit access only from a dedicated administrative jump host.
Enforce strong authentication and rotate credentials for all SCG accounts, particularly low-privileged operator roles.
Deploy a reverse proxy or WAF in front of SCG with SQL injection filtering enabled until patching is complete.

bash

# Example: restrict inbound access to SCG management interface via iptables
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
