CVE-2023-28443

### Summary CWE-532: Insertion of Sensitive Information into Log File discovered in v9.23.1. The `directus_refresh_token` is not redacted properly from the log outputs and can be used to impersonate users without their permission. ### Details Using `v9.23.1`, I am seeing that the `directus_refresh_token` is not properly redacted as indicated by https://github.com/directus/directus/blob/7c479c5161639aac466c763b6b958a9524201d74/api/src/logger.ts#L13 I'm classifying this as a security vulnerability because if someone has access to the log outputs, for example with a shared Cloud account or Splunk implementation, they could exchange the refresh token using `/auth/refresh` for an access token and use the token to perform actions on behalf of an unsuspecting user. This situation creates issues with accountability and non-repudiation because we can no longer have confidence that actions taken in the application were authorized or even performed by the logged-in user. A couple of examples of this are: - A disgruntled employee deletes all of the data to get even with a target team member before logging off on their last day - Under the guise of their unsuspecting boss, a mischievous engineer uploads _questionable_ images that get displayed on internal or external facing content sites The list could go on but I think these communicate the risk of an internal threat that has access to this information 😆 ### PoC 1. Set `LOG_STYLE="raw"` and run Directus v9.23.1 1. Log in to the application 1. Look at the shell output and see that `directus_refresh_token` is logged > Note: This is different from the standard `raw` output format. I intentionally ran this with `npx directus start | pino-pretty` so logs would be easier to read. It can also be reproduced by running `npx directus start` alone.  1. Exchange the `directus_refresh_token` for an `access_token` ``` shell curl -X POST \ 'http://0.0.0.0:8055/auth/refresh' \ --header 'Accept: */*' \ --header 'Cookie: directus_refresh_token=$shh' ``` ### Impact Because this can be used to exploit other threats related to [CWE-284: Improper Access Control](https://cwe.mitre.org/data/definitions/284.html) I rank it with a Moderate severity. An insider with knowledge of this could do many mischievous things and get away with them for a long time without victims knowing about it.
