org.openidentityplatform.openam:openam-core-rest
source listed<= 16.0.6
OpenAM (Open Identity Platform) is an open-source IAM platform providing SSO, OAuth2, SAML, and OpenID Connect capabilities. The CREST REST API layer exposes user query endpoints under `/json/{realm}/users`. In `IdentityResourceV1.queryCollection()`, the HTTP query parameter `_queryId` is passed to a `CrestQuery` object with `escapeQueryId` **explicitly set to `false`**, bypassing the escape protection introduced as part of the CVE-2021-29156 fix. The unescaped value flows directly to `DJLDAPv3Repo.getFilter()` where it is concatenated into an LDAP filter string without sanitization, enabling authenticated attackers to inject arbitrary LDAP metacharacters for user enumeration and blind LDAP injection. ## Affected Endpoint | Endpoint | Auth Required | Injection Parameter | |----------|--------------|---------------------| | `GET /openam/json/{realm}/users?_queryId=` | SSO Token | `_queryId` | | `GET /openam/json/{realm}/groups?_queryId=` | SSO Token (TBD) | `_queryId` | ## Background: CVE-2021-29156 CVE-2021-29156 was a pre-authentication LDAP injection in OpenAM's Webfinger endpoint, where user-supplied input reached `DJLDAPv3Repo.getFilter()` unescaped.

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
