A vulnerability was found in 3Scale when using with Keycloak 15 (or RHSSO 7.5.0) and superiors. When the authtype is use3scaleoidcissuerendpoint, Token Introspection policy discovers the Token Introspection endpoint from the tokenintrospectionendpoint field, but the field was removed on RH-SSO 7.5. As the result, the policy doesn't inspect tokens; it determines that all tokens are valid.

Using an alternate authtype: authtype: clientid+clientsecret. Disabling the policy entirely might be a temporary solution if the alternate {{authtype is not feasible for some reason. The only purpose the token introspection endpoint serves is for sessions which are revoked in RH SSO before the standard TTL expires via the exp claim.

A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients.

A flaw was found in Keycloak. This flaw allows impersonation and lockout due to the email trust not being handled correctly in Keycloak. An attacker can shadow other users with the same email and lockout or impersonate them.

A flaw was found in undertow. The undertow client is not checking the server identity the server certificate presents in HTTPS connections. This is a compulsory step ( that should at least be performed by default) in HTTPS and in http/2.

A flaw was found in Keycloak package. This flaw allows an attacker to benefit from Cross-Site Scripting by sending a script via URL. This flaw requires a user or administrator to interact with a link in order to be vulnerable. This may compromise the user details, may it be changed or collected by the attacker. An administrator who might be affected may also compromise the server data.

A flaw was found in Red Hat Single Sign-On for OpenShift container images, which are configured with an unsecured management interface enabled. This flaw allows an attacker to use this interface to deploy malicious code and access and modify potentially sensitive information in the app server configuration.

A flaw was found in the offlineaccess scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user.

/clients-registrations/openid-connect could consume an invalidated token and register a new client.

Reproducer: 1. Generate a token for service-account using the clientcredentials flow 2. Revoke the token using the /revoke endpoint passing in the above token. 3. Now, invoke /clients-registrations/openid-connect passing in the above generated token for auth 4. A client is created using the token

A flaw was found in Undertow with EJB invocations. This flaw allows an attacker to generate a valid HTTP request and send it to the server on an established connection after removing the LASTCHUNK from the bytes, causing a denial of service.

A Stored Cross-site scripting (XSS) vulnerability was found in keycloak as shipped in Red Hat Single Sign-On 7. This flaw allows a privileged attacker to execute malicious scripts in the admin console, abusing the default roles functionality.

A flaw was found in Undertow. For an AJP 400 response, EAP 7 is improperly sending two response packets, and those packets have the reuse flag set even though JBoss EAP closes the connection. A failure occurs when the connection is reused after a 400 by CPING since it reads in the second SENDHEADERS response packet instead of a CPONG.

A flaw was found in WildFly, where an attacker can see deployment names, endpoints, and any other data the trace payload may contain.

A flaw was found in Keycloak in the execute-actions-email endpoint. This issue allows arbitrary HTML to be injected into emails sent to Keycloak users and can be misused to perform phishing or other attacks against users.

A flaw was found in Undertow where a potential security issue in flow control handling by browser over HTTP/2 may potentially cause overhead or DOS in the server. The highest impact of this vulnerability is availability.(incomplete fix for CVE-2021-3629)
