OpenAM vulnerabilities

OpenAM 10.1.0 has an XXE (XML External Entity) vulnerability in the path /SSOPOST/metaAlias/%realm%/idpv2, allowing remote attackers to read arbitrary files via the SAMLRequest parameter.

In OpenAM prior to 16.1.2, the pre-authentication /authservice PLL endpoint accepts a CustomCallback XML element whose className value selects an arbitrary Java class for AuthXMLUtils to load and instantiate without verifying it implements DSAMECallbackInterface. Default configurations expose the endpoint without authentication, allowing attacker-controlled class initialization and unsafe deserialization to execute code in the server process. Enabling sunRemoteAuthSecurityEnabled does not prevent the vulnerable parsing because its check occurs later.

In OpenAM prior to 16.1.2, WebAuthnAuthentication.deserialize applies an ObjectInputFilter that allows every serialized object at depth greater than 1, constraining only an AuthenticatorImpl root object. A pre-authentication attacker can supply a userHandle whose serialized graph has a valid AuthenticatorImpl root and a nested gadget class, causing readObject or readResolve execution before cast and assertion verification. This bypasses the incomplete remediation for the earlier WebAuthn deserialization vulnerability.

In OpenAM prior to 16.1.1, AuthorizationCodeGrantTypeHandler requires a code_verifier only when the realm-wide codeVerifierEnforced setting is enabled, even when an authorization code stores a code_challenge. Because that setting is disabled by default, an attacker who intercepts a PKCE-protected authorization code can omit code_verifier and redeem the code. Public clients are directly affected, and confidential-client exploitation additionally requires client authentication material.

In OpenAM 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.

In OpenAM prior to 16.1.1, the Liberty Web Services SOAP receiver permits unauthenticated remote requests to write persistent entries through SOAPReceiver and DiscoveryService into a user's Liberty Discovery store and the shared root-realm Discovery branch. The server-side handlers bypass requester LDAP and identity ACLs, and the global path uses an internal administrative token. Deployments that consume Liberty discovery data can subsequently use manipulated service-routing or security-mechanism records.

In OpenAM prior to 16.1.1, WebAuthnAuthentication loads a serialized AuthenticatorImpl object graph from the configured userAttribute through loadAuthenticators without an ObjectInputFilter. Exploitation requires the WebAuthn flow to be reachable and an attacker to have previously written controlled data to that attribute through delegated administration, provisioning, directory access, legacy REST self-registration, or unsafe configuration. When those conditions hold, the data is deserialized before assertion verification and can execute a classpath gadget in the application server process.

OpenAM prior to 16.0.6 is vulnerable to pre-authentication Remote Code Execution (RCE) via unsafe Java deserialization of the jato.clientSession HTTP parameter, bypassing the WhitelistObjectInputStream mitigation applied to jato.pageSession after CVE-2021-35464.

OpenAM up to version 14.7.2 does not properly validate the signature of SAML responses in the SSO process, allowing attackers to impersonate any OpenAM user, including the administrator.

OpenAM before 16.1.3 contains a server-side request forgery vulnerability. Attackers able to register or modify OAuth 2.0 clients can make OpenAM fetch internal resources via an unvalidated jwks_uri. They can trigger unauthenticated fetches to probe internal hosts, metadata endpoints or local files, or exhaust request threads for DoS.

OpenAM before 16.1.3 contains an improper authorization vulnerability that allows delegated administrators to destroy sessions outside their realms because realm checks use the requester's realm. Authenticated accounts holding the iplanet-am-session-destroy-sessions attribute can supply a target session identifier or handle to forcibly log out users in any realm.

OpenAM before 16.1.3 contains an authorization bypass vulnerability in the sessions REST endpoint query operation that allows realm administrators to list sessions of every realm. Attackers holding delegated RealmAdmin privileges can supply a _queryFilter naming another realm to disclose usernames, universal IDs, and session handles across tenant boundaries.

OpenAM before 16.1.3 applies its OAuth2 Provider PKCE enforcement only to authorization requests whose response_type is exactly 'code'. Codes issued through OpenID Connect hybrid flows (code token, code id_token, code token id_token) carry no bound challenge. An attacker who intercepts such a code can redeem it for a public client's tokens with any non-empty code_verifier.

OpenAM before 16.1.3 contains an open redirect vulnerability that allows unauthenticated attackers to redirect users by supplying an unverified id_token_hint to the /oauth2/connect/endSession endpoint. Attackers can name any realm client in a forged hint to redirect victims to any registered post-logout URI, enabling phishing that borrows the OpenAM host's trust.

OpenAM before 16.1.3 contains an email content injection vulnerability that allows unauthenticated attackers to control notification email wording via the forgotPassword and register actions on /json/{realm}/users. Attackers can supply subject and message fields to send phishing mail from the organisation's configured From address, or abuse register as a relay to arbitrary recipients.

OpenAM before 16.1.3 contains a latent cross-site scripting defect that places the SAML message, relay state and target URL unencoded into the load-balancer cookie bounce auto-submit page. If reachable with cookieHashRedirectEnabled set, crafted requests could execute script in the OpenAM origin, though an unrelated HTTP 500 failure prevents exploitation in released versions.

OpenAM before 16.1.3 contains an unauthenticated arbitrary class instantiation vulnerability in the legacy JAX-RPC SOAP interface. Remote attackers can send SOAP requests to /jaxrpc/* with an unverified session identifier and a chosen class name, crashing the server, probing the classpath, or potentially reaching code execution.

OpenAM before 16.1.3 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject script by supplying crafted parameters rendered unencoded on the OAuth2 authorization error page. Attackers can lure victims to a crafted /oauth2/authorize link with repeated parameters to run JavaScript in the OpenAM origin, acting within existing sessions or redirecting to phishing pages.

OpenAM from version 13.0.0 to 16.1.2 has a reflected XSS vulnerability in the OAuth2 authorize endpoint's display=wap consent page. The page reflects request-derived values without HTML escaping, allowing an attacker to execute JavaScript in the OpenAM origin, enabling session or cookie theft, CSRF-token disclosure, and actions with the victim's privileges. At least one registered OAuth2 client is required, but the attacker does not need to control that client.

In OpenAM, the default configuration initializes the iPlanetDirectoryPro SSO cookie with HttpOnly disabled and without a protective SameSite default, and OAuth and OpenID Connect consent flows reuse that cookie through CsrfProtection as a CSRF token. When combined with same-origin cross-site scripting and a user following an attacker-controlled link, the cookie can be read and reused to steal the SSO session and complete attacker-driven consent grants. This issue is fixed in version 16.1.1.

In OpenAM, the private_key_jwt client authentication path uses ClientJwksResolverCache without reliably binding a cached jwks_uri resolver and verified assertion to the expected clientID in ClientCredentialsReader. An attacker controlling any registered client with published keys, including one obtained through open dynamic registration when enabled, can authenticate as another client whose keys are exposed through jwks_uri and mint tokens in that client's name across realms in the same OpenAM process. This issue is fixed in version 16.1.1.

In OpenAM, GroovySandboxValueFilter permits an authenticated server-side script author to escape the scripting sandbox despite the default class allow and deny lists. A user such as a sub-realm RealmAdmin who can create or edit a script in an executed context can invoke operating-system commands as the OpenAM application server account, crossing the realm-scoped administration boundary and compromising the JVM and every realm it serves. This issue is fixed in version 16.1.1.

In OpenAM, the OAuth2 authentication module updates an existing local account with profile attributes that can include userPassword and inetUserStatus, rewriting the password to the username and reactivating disabled accounts. The missing OAuth.removeRestrictedAccountUpdateAttributes filtering permits these credential and status fields to reach the account update. With account creation enabled, repeated OAuth login causes the default ldapService chain to accept the username as both identifier and password, allowing an unauthenticated attacker to take over the local account without interacting with the identity provider. This issue is fixed in version 16.1.1.

In OpenAM, OAuthTokenStore reads caller-supplied token identifiers from the shared Core Token Store (CTS) without an OAuth-only namespace, and OAuthAdapter accepts a row whose BLOB claims to contain an OAuth token without binding the trusted CTS type or verifying integrity. An attacker who can place controlled JSON in CTS under a known token identifier, such as through Push Registration followed by an anonymous SNS callback in an enabled realm, can mint OAuth bearer tokens and OpenID Connect ID tokens with chosen subject, client, realm, and scope. This issue is fixed in version 16.1.1.

In OpenAM, the anonymous Push Notification SNS callback handled by SnsMessageResource falls back to a CTS predicate blob after a messageId expires from the in-memory dispatcher, treats top-level blob keys as Java class names for Class.forName, and deserializes attacker-controlled JSON through Jackson. A low-privileged user who starts Push Registration and obtains the messageId, shared secret, and challenge can wait for expiry, replace the persistent blob through anonymous callbacks, and trigger class loading and construction in the OpenAM JVM. This issue is fixed in version 16.1.1.

In OpenAM, SessionRequestHandler in the session management endpoint does not enforce ownership or privilege checks when a low-privileged authenticated user queries session information in deployments using stateful session storage. A requester who knows a target identity identifier can retrieve another user's active session credentials, including credentials for a more privileged account, and use them to hijack that session. This issue is fixed in version 16.1.1.

In OpenAM prior to 16.1.1, certain federation endpoints in a non-default clustered configuration inconsistently encode user-supplied parameters rendered into HTML in the SAML2 cluster cookie-hash redirect path. An unauthenticated attacker can induce a user to follow a crafted request and execute script in the OpenAM origin. This issue is fixed in version 16.1.1.

In OpenAM prior to 16.1.1, the OAuth 2.0 and OpenID Connect authorization endpoint does not sufficiently encode user-supplied parameters before FormPostResponse.ftl and checkSession.ftl render them into HTML for the form_post response mode. An unauthenticated attacker can induce a user to open a crafted authorization request and execute script in the OpenAM origin. This issue is fixed in version 16.1.1.

OpenAM prior to version 16.1.1 has a vulnerability in the /sessionservice addSessionListener operation that allows an authenticated user to register an arbitrary notification URL without requiring an administrative or application client token. The OpenAM server may make outbound requests to an attacker-controlled destination, potentially disclosing session-related notification data.

In OpenAM 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.
