CVE-2026-56088: Dell OpenManage Enterprise SQLi Vulnerability

CVE-2026-56088 Overview

CVE-2026-56088 is an SQL injection vulnerability affecting Dell OpenManage Enterprise versions prior to 4.7.0. The flaw stems from improper neutralization of special elements used in an SQL command [CWE-89]. A low-privileged attacker with remote network access can exploit this weakness to achieve script injection against the management console. Dell disclosed the issue in security advisory DSA-2026-359 and released a fix in version 4.7.0.

Critical Impact
An authenticated remote attacker with low privileges can inject SQL commands into Dell OpenManage Enterprise, resulting in high confidentiality impact and limited availability disruption across managed infrastructure.

Affected Products

Dell OpenManage Enterprise versions prior to 4.7.0
Dell server infrastructure managed through affected OpenManage Enterprise instances
Deployments exposing the OpenManage Enterprise web interface to authenticated users

Technical Details for CVE-2026-56088

Vulnerability Analysis

Dell OpenManage Enterprise is a systems management console used to monitor and administer Dell server hardware. The vulnerability exists because user-supplied input is concatenated into SQL statements without adequate neutralization of special characters. An authenticated attacker holding low-privileged credentials can submit crafted parameters through the network-accessible interface. The database engine then interprets the injected fragments as syntactically valid SQL, altering the intended query logic.

The advisory characterizes the downstream impact as script injection, indicating that the injected SQL payload can influence content that is later rendered or executed in another context. This chained behavior expands the practical impact beyond direct data manipulation. Confidentiality is rated high because the underlying database may contain inventory, credential material, and configuration data for managed systems.

Root Cause

The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. Application code paths accept parameter values and place them directly into SQL statements without parameterized queries or strict input validation. This design allows metacharacters such as single quotes, semicolons, and comment sequences to break query boundaries.

Attack Vector

The attack vector is network-based and requires low-privilege authentication. No user interaction is required, and the attack complexity is low. An attacker with valid credentials to the OpenManage Enterprise console sends a crafted HTTP request containing SQL syntax in a vulnerable parameter. The backend concatenates the payload into a database query, and the resulting response or stored value carries injected content that can trigger script execution in subsequent workflows.

No public proof-of-concept exploit or exploitation activity has been documented at the time of publication. Refer to the Dell Security Update DSA-2026-359 for vendor technical details.

Detection Methods for CVE-2026-56088

Indicators of Compromise

Unusual SQL metacharacters such as ', --, ;, or UNION SELECT appearing in OpenManage Enterprise HTTP request logs
Database error messages surfaced in application responses following requests from authenticated low-privileged accounts
Unexpected script content stored in fields displayed by the OpenManage Enterprise console
Anomalous query patterns or long-running database calls originating from the OpenManage Enterprise application service account

Detection Strategies

Inspect web server and reverse proxy logs for requests containing SQL syntax against OpenManage Enterprise API and UI endpoints
Baseline normal parameter values used by authenticated sessions and alert on payloads containing SQL keywords or encoded variants
Correlate authentication events for low-privileged OpenManage Enterprise accounts with subsequent anomalous query volume against the backend database

Monitoring Recommendations

Enable verbose application and database audit logging on OpenManage Enterprise appliances until patching is complete
Forward OpenManage Enterprise logs to a centralized analytics platform for retention and correlation across administrative sessions
Monitor outbound connections from the OpenManage Enterprise host for unexpected destinations that could indicate post-exploitation activity

How to Mitigate CVE-2026-56088

Immediate Actions Required

Upgrade Dell OpenManage Enterprise to version 4.7.0 or later as specified in DSA-2026-359
Audit and reduce the number of accounts with access to the OpenManage Enterprise console, removing unused low-privileged accounts
Rotate credentials for any OpenManage Enterprise accounts suspected of misuse prior to patching
Review database contents and stored fields for injected script payloads that may execute in subsequent user sessions

Patch Information

Dell has released a fixed build in Dell OpenManage Enterprise version 4.7.0. Administrators should follow the guidance published in the Dell Security Update DSA-2026-359 advisory, which lists the affected versions and remediation steps. Apply the update in a maintenance window and validate console functionality after the upgrade.

Workarounds

Restrict network access to the OpenManage Enterprise management interface using firewall rules or management VLAN segmentation
Enforce multi-factor authentication and least privilege for all OpenManage Enterprise accounts to reduce the pool of potential attackers
Place a web application firewall in front of the OpenManage Enterprise interface with rules that block common SQL injection patterns until patching completes

bash

# Example firewall restriction limiting console access to a dedicated management subnet
iptables -A INPUT -p tcp --dport 443 -s 10.10.50.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
