GHSA-R64V-82FH-XC63

Vulnerability from github – Published: 2025-07-09 15:30 – Updated: 2025-07-09 15:30

Summary

Juju vulnerable to sensitive log retrieval via authenticated endpoint without authorization

Details

Impact

Any user with a Juju account on a controller can read debug log messages from the /log endpoint. No specific permissions are required - it's just sufficient for the user to exist in the controller user database. The log messages may contain sensitive information.

Details

The /log endpoint is accessible at the following endpoints: - wss://<controller-ip>/log - wss://<controller-ip>/model/<model-uuid>/log

In order to connect to these endpoints, the client must pass an X-Juju-Client-Version header that matches the current version and pass credentials in a Basic Authorization header. Once connected, the service will stream log events even though the user is not authorised to view them.

To reproduce:

juju bootstrap
juju add-user testuser
juju change-user-password testuser

Run the wscat command below to connect to wss://<controller-ip>:17070/api. Update the JSON payload to include the username and password that were created above.

wscat --no-check -c wss://contorller-ip:17070/model/modelUUID/api
{ "type": "Admin", "request": "Login", "version": 3, "params": { "client-
version": "3.6.1.0", "auth-tag": "user-testuser", "credentials": "
password" } }

Observe that the connection fails due to a lack of permissions.

Run the command below to connect to the log endpoint. Note that the credentials are passed in the --auth flag.

wscat --auth user-testuser:password -H "X-Juju-ClientVersion: 3.6.4" --no-check -c wss://<controller-ip>:17070/log

Observe that the logs are returned in the server’s response.

Code

The /log handlers are registered here https://github.com/juju/juju/blob/3.6/apiserver/apiserver.go#L867 https://github.com/juju/juju/blob/3.6/apiserver/apiserver.go#L980

And the only auth required is that the incoming request be for an authenticated user

https://github.com/juju/juju/blob/3.6/apiserver/apiserver.go#L713

but no specific permission checks are done.

Workarounds

There are no workarounds.

  "details": "### Impact\nAny user with a Juju account on a controller can read debug log messages from the `/log` endpoint.\nNo specific permissions are required - it\u0027s just sufficient for the user to exist in the controller user database.\nThe log messages may contain sensitive information.\n\n### Details\n\nThe `/log` endpoint is accessible at the following endpoints:\n- `wss://\u003ccontroller-ip\u003e/log`\n- `wss://\u003ccontroller-ip\u003e/model/\u003cmodel-uuid\u003e/log`\n\nIn order to connect to these endpoints, the client must pass an X-Juju-Client-Version header that matches the current version and pass credentials in a Basic Authorization header. Once connected, the service will stream log events even though the user is not authorised to view them.\n\nTo reproduce:\n\n```\njuju bootstrap\njuju add-user testuser\njuju change-user-password testuser\n```\nRun the [wscat](https://github.com/websockets/wscat) command below to\nconnect to `wss://\u003ccontroller-ip\u003e:17070/api`. Update the JSON payload to include the username and password that were created above.\n\n```\nwscat --no-check -c wss://contorller-ip:17070/model/modelUUID/api\n{ \"type\": \"Admin\", \"request\": \"Login\", \"version\": 3, \"params\": { \"client-\nversion\": \"3.6.1.0\", \"auth-tag\": \"user-testuser\", \"credentials\": \"\npassword\" } }\n```\n\nObserve that the connection fails due to a lack of permissions.\n\nRun the command below to connect to the log endpoint. Note that the credentials are passed in the --auth flag.\n\n```\nwscat --auth user-testuser:password -H \"X-Juju-ClientVersion: 3.6.4\" --no-check -c wss://\u003ccontroller-ip\u003e:17070/log\n```\n\nObserve that the logs are returned in the server\u2019s response.\n\n### Code\n\nThe `/log` handlers are registered here\nhttps://github.com/juju/juju/blob/3.6/apiserver/apiserver.go#L867\nhttps://github.com/juju/juju/blob/3.6/apiserver/apiserver.go#L980\n\nAnd the only auth required is that the incoming request be for an authenticated user\n\nhttps://github.com/juju/juju/blob/3.6/apiserver/apiserver.go#L713\n\nbut no specific permission checks are done.\n\n### Workarounds\nThere are no workarounds.\n\n### References\n[F-01](https://drive.google.com/file/d/1pHRNiaA8LyMVJYwIyTqelsqJ9FmImDf0/view)",
