Dell OpenManage Server Administrator Hard-coded Credentials Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-81440

Dell OpenManage Server Administrator is a management service commonly deployed to provide remote administration and monitoring for servers. While typically intended for internal use, such management interfaces are frequently exposed to network segments or remote access points, making them a common target for network-based access in many enterprise deployment environments.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory addresses a critical vulnerability in Dell's OpenManage Server Administrator software. The issue stems from hard-coded credentials, which could allow an unauthenticated remote attacker to gain unauthorized access to affected systems. The primary concern is confirming whether this specific software is in use and exposed within the environment, as its management functions could be compromised.

  • Hard-coded credentials allow remote unauthorized access.
  • Critical vulnerability in Dell server management software.
  • Confirm relevance and exposure for affected Dell systems.

Attack Path

How an attacker could exploit the issue

An attacker can remotely access Dell OpenManage Server Administrator, a management service for servers. If they can reach this service over the network, they may be able to exploit a weakness involving hard-coded credentials to gain unauthorized access to the system.

  • Unauthenticated remote network access required.
  • Vulnerable component with hard-coded credentials.
  • Results in unauthorized system access.

Live Threat

Current exploitation, exposure, and threat context

An unauthenticated attacker with remote access could exploit this vulnerability to gain unauthorized access to systems running Dell OpenManage Server Administrator. This could potentially expose sensitive system information or allow for malicious modification of server configurations.

  • System management data.
  • Remote unauthenticated network access.
  • Unauthorized system access.

Operational Fix

Recommended remediation, mitigation, and detection steps

Dell OpenManage Server Administrator is a management tool, suggesting that platform or infrastructure teams are likely responsible for its upkeep. Given the potential for unauthorized remote access, the immediate priority is to confirm the presence and exposure of this technology within your environment and identify the accountable owner to initiate a risk-based remediation plan.

  • Platform or infrastructure team ownership.
  • Verify external reachability and business criticality.
  • Plan remediation based on exposure and risk.

Frequently asked questions

What is Dell OpenManage Server Administrator?

It is a web-based management suite used by IT teams to remotely monitor, configure, and manage Dell PowerEdge servers. By providing a centralized interface for hardware health and system settings, it simplifies infrastructure maintenance but also centralizes control over the server's operational environment.

What does the hard-coded credentials vulnerability in CVE-2026-81440 mean?

This vulnerability, classified as CWE-798, means the software contains authentication information—such as a username or password—that is built directly into the program's code. Because these credentials cannot be easily changed or removed by the user, an attacker who knows them can bypass standard login security to access the system without permission.

How does an attacker trigger this vulnerability?

An attacker triggers this bug by reaching the software's network service and using the hard-coded credentials to authenticate. The vulnerability is not triggered by standard local server usage; it specifically requires remote network connectivity to the management interface. If the service is entirely isolated from the network, the attack path is not available.

Is my server at risk according to Halo Surface Signal?

Halo Surface Signal indicates that while this software is designed for internal management, these interfaces are often inadvertently accessible via broader network segments or remote access points. If your server's management port is reachable from outside your trusted internal network, it is considered externally exposed and at higher risk.

What should I do if I am running this software?

First, identify which servers in your environment are running versions prior to 11.1.0.3. Coordinate with your infrastructure or platform team to confirm if the management service is reachable over the network. The primary step is to apply the security update provided by Dell to remove the hard-coded credentials and secure the administrative interface.
