Sources and claim methodology

Upstream source description

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, IdentityResourceV1.queryCollection() passes the _queryId parameter from /json/{realm}/users to CrestQuery with escapeQueryId disabled, bypassing protection added for CVE-2021-29156. The unescaped value reaches DJLDAPv3Repo.getFilter(), where it is concatenated into an LDAP filter, allowing an authenticated attacker to inject LDAP metacharacters for user enumeration and blind LDAP injection. This issue is fixed in version 16.1.1.
