IBM DataPower Gateway Empty Password Bypass Allows Administrative Access.

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-14502

IBM DataPower Gateway is an enterprise-grade internet edge gateway designed to handle traffic at the network perimeter. It functions as a reverse proxy, API gateway, and security enforcement point, making it public-facing by design in normal deployment scenarios to facilitate external service communication.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability affects IBM DataPower Gateway, a critical network edge device, and could allow unauthorized access to administrative functions by exploiting a weakness in how it handles authentication. The primary concern is confirming if this technology is relevant to our environment and assessing any potential exposure.

  • Weak password handling grants admin access.
  • Protects critical network edge systems.
  • Confirm relevance and assess exposure.

Attack Path

How an attacker could exploit the issue

An attacker could gain administrative access to an IBM DataPower Gateway by exploiting a vulnerability related to how it handles empty passwords during LDAP authentication. If an attacker can reach the LDAP authentication feature, they might be able to bypass authentication and obtain elevated privileges.

  • Network access is required.
  • Empty passwords are not rejected.
  • Unauthenticated administrative access results.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, an attacker could gain administrative access to IBM DataPower Gateway through a network-based attack that exploits the system's failure to reject empty passwords during LDAP authentication. This could potentially expose sensitive system configurations and operational controls.

  • Administrative access to the gateway.
  • Network access with no user interaction.
  • Compromise of system functions and data.

Operational Fix

Recommended remediation, mitigation, and detection steps

Teams responsible for IBM DataPower Gateway infrastructure and its security configuration should address this vulnerability. The first step is to identify all DataPower instances, determine their network exposure, confirm business criticality, and ascertain the specific team or individual accountable for each instance before planning remediation.

  • Identify affected DataPower instances.
  • Verify external reachability and business impact.
  • Plan remediation with the accountable owner.

Frequently asked questions

What is IBM DataPower Gateway?

IBM DataPower Gateway is an enterprise-grade network edge device. Organizations use it as a reverse proxy, API gateway, and security enforcement point to manage traffic flow and protect internal resources at the network perimeter.

How does CVE-2026-14502 impact authentication?

This vulnerability is classified as Improper Authentication (CWE-287). It occurs because the gateway fails to properly reject empty passwords during LDAP authentication, which can allow an attacker to bypass security checks and gain administrative access.

Can any LDAP request trigger this vulnerability?

The flaw specifically triggers when the gateway processes an authentication attempt with an empty password. It does not occur if the system is configured to use non-LDAP authentication methods or if the LDAP implementation correctly validates password fields before processing.

Is my IBM DataPower Gateway at risk?

According to Halo Surface Signal, these gateways are typically internet-facing by design to handle external traffic. If your instance is reachable over the network and uses LDAP for authentication, it is likely exposed to this threat.

What should I do to secure my environment?

Start by identifying all deployed DataPower instances and their specific network configurations. Determine which ones use LDAP authentication and confirm the business criticality of those assets to prioritize your response planning.
