CVE-2026-44272: Dell Wyse Management Suite SQL Injection

CVE-2026-44272 Overview

CVE-2026-44272 is an SQL Injection vulnerability affecting Dell Wyse Management Suite (WMS) versions prior to WMS 2605. The flaw stems from improper neutralization of special elements used in an SQL command [CWE-89]. A remote attacker holding low-privileged credentials can inject crafted SQL statements through the application interface. Successful exploitation leads to unauthorized access to the underlying database, with potential impact on confidentiality, integrity, and availability of managed thin client data.

Critical Impact
A low-privileged remote attacker can manipulate SQL queries to access or modify sensitive data managed by Dell Wyse Management Suite, including credentials and device configuration records.

Affected Products

Dell Wyse Management Suite (WMS) versions prior to 2605
Deployments using WMS for thin client and endpoint device management
On-premises and private cloud WMS installations exposed to authenticated users

Technical Details for CVE-2026-44272

Vulnerability Analysis

The vulnerability resides in Dell Wyse Management Suite, a centralized platform for managing Wyse thin clients and endpoint devices. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries. An authenticated user with limited privileges can submit crafted input that the backend database interprets as SQL syntax rather than data.

Because the attack vector is network-based and requires only low privileges with no user interaction, any account with access to the WMS web interface can attempt exploitation. Successful injection grants the attacker the ability to read sensitive records, alter data, and potentially escalate access within the management database.

Root Cause

The root cause is the improper neutralization of special characters in SQL commands, classified under [CWE-89]. Input fields accessible to authenticated users are concatenated into SQL statements without parameterized queries or sufficient input validation. This allows special elements such as quotes, semicolons, and SQL keywords to break query context.

Attack Vector

The attacker authenticates to WMS using any low-privileged account, then submits crafted parameters to a vulnerable endpoint over the network. The injected payload executes against the WMS database, returning results or modifying records outside the attacker's authorization scope. Refer to the Dell Security Advisory DSA-2026-247 for vendor-confirmed technical details.

Detection Methods for CVE-2026-44272

Indicators of Compromise

Unexpected SQL syntax patterns (UNION SELECT, OR 1=1, --, ;) in WMS application logs or HTTP request parameters
Database queries originating from low-privileged WMS user sessions accessing tables outside their normal scope
Authentication events followed by anomalous database response times or error messages
New or modified administrator accounts in the WMS database without corresponding administrative activity

Detection Strategies

Enable verbose query logging on the WMS database server and review for malformed or unexpected SQL statements
Deploy web application firewall rules to flag SQL metacharacters in WMS HTTP request bodies and query strings
Correlate authentication logs with database query patterns to identify low-privileged accounts performing privileged operations

Monitoring Recommendations

Monitor WMS administrative endpoints for repeated requests with abnormal parameter content
Alert on database error messages returned to WMS users, which may indicate injection probing
Track outbound data volume from the WMS database to detect bulk extraction attempts

How to Mitigate CVE-2026-44272

Immediate Actions Required

Upgrade Dell Wyse Management Suite to version 2605 or later as directed by Dell Security Advisory DSA-2026-247
Audit all WMS user accounts and remove or disable any inactive or unnecessary low-privileged accounts
Restrict network access to the WMS management interface to trusted administrative networks only
Review WMS and database logs for evidence of prior exploitation attempts

Patch Information

Dell has released a fixed version in Wyse Management Suite 2605. Administrators should consult Dell Security Advisory DSA-2026-247 for the official remediation package and upgrade instructions. Apply the patch in accordance with your organization's change management procedures.

Workarounds

Place WMS behind a web application firewall configured with SQL injection detection rules until patching is complete
Enforce network segmentation so that only authorized administrators can reach the WMS interface
Rotate credentials for all WMS user accounts after applying the patch to invalidate any tokens that may have been exposed

bash

# Example: restrict WMS access via host-based firewall (Linux iptables)
iptables -A INPUT -p tcp --dport 443 -s 10.0.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
