CVE-2024-45596 (GCVE-0-2024-45596)

Vulnerability from cvelistv5 – Published: 2024-09-10 18:43 – Updated: 2024-09-10 19:20

Title

Directus's session is cached for OpenID and OAuth2 if `redirect` is not used

Summary

Directus is a real-time API and App dashboard for managing SQL database content. An unauthenticated user can access credentials of last authenticated user via OpenID or OAuth2 where the authentication URL did not include redirect query string. This happens because on that endpoint for both OpenId and Oauth2 Directus is using the respond middleware, which by default will try to cache GET requests that met some conditions. Although, those conditions do not include this scenario, when an unauthenticated request returns user credentials. This vulnerability is fixed in 10.13.3 and 11.1.0.

Severity ?

7.4 (High)

Un usuario no autenticado puede acceder a las credenciales del \u00faltimo usuario autenticado a trav\u00e9s de OpenID u OAuth2 donde la URL de autenticaci\u00f3n no inclu\u00eda una cadena de consulta de redireccionamiento. Esto sucede porque en ese endpoint, tanto para OpenID como para OAuth2, Directus usa el middleware de respuesta, que de manera predeterminada intentar\u00e1 almacenar en cach\u00e9 las solicitudes GET que cumplieron con algunas condiciones. Sin embargo, esas condiciones no incluyen este escenario, cuando una solicitud no autenticada devuelve las credenciales del usuario. Esta vulnerabilidad se corrigi\u00f3 en 10.13.3 y 11.1.0."

Vulnerability from github – Published: 2024-09-10 19:43 – Updated: 2025-11-17 21:35

Summary

Session is cached for OpenID and OAuth2 if `redirect` is not used

Details

Summary

Unauthenticated user can access credentials of last authenticated user via OpenID or OAuth2 where the authentication URL did not include redirect query string.

For example: - Project is configured with OpenID or OAuth2 - Project is configured with cache enabled - User tries to login via SSO link, but without redirect query string - After successful login, credentials are cached - If an unauthenticated user tries to login via SSO link, it will return the credentials of the other last user

The SSO link is something like https://directus.example.com/auth/login/openid/callback, where openid is the name of the OpenID provider configured in Directus

Details

This happens because on that endpoint for both OpenId and Oauth2 Directus is using the respond middleware, which by default will try to cache GET requests that met some conditions. Although, those conditions do not include this scenario, when an unauthenticated request returns user credentials. For OpenID, this can be seen here: https://github.com/directus/directus/blob/main/api/src/auth/drivers/openid.ts#L453-L459 And for OAuth2 can be seen here https://github.com/directus/directus/blob/main/api/src/auth/drivers/oauth2.ts#L422-L428

PoC

Create a new Directus project
Set CACHE_ENABLED to true
Set CACHE_STORE to redis for reliable results (if using memory with multiple nodes, it may only happen sometimes, due to cache being different for different nodes)
Configure REDIS with redis string or redis host, port, user, etc.
Set AUTH_PROVIDERS to openid
Set PUBLIC_URL to the the main URL of your project . For example, PUBLIC_URL: http://localhost:8055
Configure AUTH_OPENID_CLIENT_ID, AUTH_OPENID_CLIENT_SECRET, AUTH_OPENID_ISSUER_URL with proper OpenID configurations
Be sure that on OpenID external app you have configured Redirect URI to http://localhost:8055/auth/login/openid/callback
Run Directus
Open the SSO link like http://localhost:8055/auth/login/openid/callback
Do the authentication on the OpenID external webpage
Verify that it you got redirected to a page with a JSON including access_token property
Be sure all anonymous mode windows are closed
Open an anonymous window and go to the SSO Link http://localhost:8055/auth/login/openid/callback and see you have the same credentials, even though you don't have any session because you are in anonymous mode

Impact

All projects using OpenID or OAuth 2, that does not include redirect query string on loggin in users.
