Detailsinfo

A vulnerability was found in OpenIdentityPlatform OpenAM up to 16.1.0 and classified as critical. Affected by this issue is the function MSISDNValidation of the component MSISDN authentication module. The manipulation of the argument MSISDN with an unknown input leads to a ldap injection vulnerability. Using CWE to declare the problem leads to CWE-90. The product constructs all or part of an LDAP query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended LDAP query when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-46619 since 05/15/2026. The exploitation is known to be easy. The attack may be launched remotely.
