CVE-2026-22764: Dell OpenManage Auth Bypass Vulnerability

CVE-2026-22764 Overview

Dell OpenManage Network Integration (OMNI) versions prior to 3.9 contain an Improper Authentication vulnerability (CWE-287). A low-privileged attacker with remote network access could potentially exploit this vulnerability to gain unauthorized access to sensitive information. This authentication flaw allows attackers to bypass certain security controls and retrieve data they should not be authorized to view.

Critical Impact

Low-privileged remote attackers can exploit improper authentication mechanisms to access sensitive information within Dell OpenManage Network Integration environments.

Affected Products

• Dell OpenManage Network Integration (OMNI) versions prior to 3.9

Technical Details for CVE-2026-22764

Vulnerability Analysis

This vulnerability falls under the Improper Authentication category (CWE-287), which occurs when an application does not properly verify that a user has been authenticated before allowing them to perform sensitive operations. In the context of Dell OpenManage Network Integration, the authentication mechanism fails to adequately validate user credentials or session state, permitting low-privileged users to access information beyond their authorization scope.

The vulnerability is remotely exploitable over the network with low attack complexity. An attacker needs only low-level privileges to initiate the attack, and no user interaction is required. While the vulnerability does not allow the attacker to modify data or disrupt availability, it does expose confidential information that could be leveraged for further attacks or reconnaissance.

Root Cause

The root cause of CVE-2026-22764 is an improper authentication implementation within Dell OpenManage Network Integration. The authentication controls do not sufficiently verify user identity or privilege levels before granting access to certain resources. This deficiency allows authenticated users with minimal privileges to access information that should be restricted to higher-privileged accounts or administrators.

Attack Vector

The attack vector for this vulnerability is network-based, meaning an attacker can exploit it remotely without physical access to the target system. The attacker must have valid low-level credentials to authenticate to the Dell OpenManage Network Integration system. Once authenticated, the attacker can leverage the improper authentication flaw to request and receive sensitive information by circumventing the intended access controls.

The exploitation process typically involves:

1. Authenticating to the OMNI system with low-privileged credentials
2. Crafting requests that target protected resources
3. Bypassing insufficient authentication checks to retrieve sensitive data
4. Exfiltrating the exposed information for further malicious purposes

Detection Methods for CVE-2026-22764

Indicators of Compromise

• Unusual access patterns from low-privileged accounts attempting to access restricted resources
• Authentication logs showing repeated requests to sensitive endpoints from accounts that should not have access
• Anomalous data retrieval activity from user accounts with limited permissions
• Unexpected API calls or web requests targeting administrative or sensitive data endpoints

Detection Strategies

• Monitor Dell OpenManage Network Integration authentication logs for suspicious access patterns
• Implement anomaly detection to identify low-privileged users accessing high-sensitivity resources
• Review access control lists and audit trails for evidence of unauthorized information retrieval
• Deploy network monitoring to detect unusual traffic patterns to OMNI management interfaces

Monitoring Recommendations

• Enable verbose logging on Dell OpenManage Network Integration to capture detailed authentication events
• Configure SIEM rules to alert on access attempts to sensitive resources by low-privileged accounts
• Regularly audit user privilege assignments and access patterns within the OMNI environment
• Implement real-time alerting for authentication anomalies and unauthorized data access attempts

How to Mitigate CVE-2026-22764

Immediate Actions Required

• Upgrade Dell OpenManage Network Integration to version 3.9 or later immediately
• Review and restrict network access to OMNI management interfaces to trusted sources only
• Audit current user accounts and ensure proper privilege assignment following the principle of least privilege
• Monitor existing OMNI deployments for signs of exploitation until patches are applied

Patch Information

Dell has released a security update to address this vulnerability. Organizations should upgrade Dell OpenManage Network Integration to version 3.9 or later to remediate CVE-2026-22764. The official security advisory and patch information is available at Dell Security Update DSA-2026-045.

Workarounds

• Restrict network access to Dell OpenManage Network Integration to trusted IP ranges and VPN connections
• Implement additional network segmentation to isolate OMNI systems from untrusted networks
• Apply strict firewall rules to limit remote access to OMNI management interfaces
• Consider disabling remote access to OMNI if not operationally required until patching is complete
