MSISDN Authentication LDAP Injection in OpenAM

Publication date: 2026-09-15

Last updated on: 2026-09-15

Assigner: GitHub, Inc.

Description
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, MSISDNValidation in the MSISDN authentication module concatenates the request-supplied MSISDN value into an LDAP search filter without escaping, while the default empty trusted-gateway list allows all traffic. In a realm where an MSISDN module is enabled in a reachable authentication chain, an unauthenticated remote attacker can inject LDAP filter metacharacters, select an arbitrary matching user, and obtain a normal authenticated OpenAM session without a password. This issue is fixed in version 16.1.1.

Executive Summary

This vulnerability is an LDAP injection flaw in OpenAM's MSISDN authentication module. It allows unauthenticated remote attackers to bypass authentication by injecting LDAP filter metacharacters into the MSISDN value. This manipulation enables attackers to select an arbitrary user and obtain a normal authenticated OpenAM session without a password.

Impact Analysis

An attacker could gain unauthorized access to OpenAM-protected systems, impersonate legitimate users, and perform actions on their behalf. This includes accessing sensitive data, modifying user permissions, or performing administrative actions without proper authentication.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR's data protection principles and HIPAA's security requirements. Organizations using vulnerable OpenAM versions may face compliance violations, legal penalties, and reputational damage due to insufficient authentication controls.

Mitigation Strategies
  • Update OpenAM to version 16.1.1 or later to patch the vulnerability.
  • Disable the MSISDN authentication module in any authentication chains if not required.
  • Restrict access to OpenAM instances by configuring the trusted-gateway list to allow only trusted IPs.
