Dev error stack trace leaking into prod in Play Framework

發布日:2022/6/3修改日:2025/11/3

描述

### Impact Play Framework, when run in dev mode, shows verbose errors for easy debugging, including an exception stack trace. Play does this by configuring its `DefaultHttpErrorHandler` to do so based on the application mode. In its Scala API Play also provides a static object `DefaultHttpErrorHandler` that is configured to always show verbose errors. This is used as a default value in some Play APIs, so it is possible to inadvertently use this version in production. It is also possible to improperly configure the `DefaultHttpErrorHandler` object instance as the injected error handler. Both of these situations could result in verbose errors displaying to users in a production application, which could expose sensitive information from the application. In particular the constructor for `CORSFilter` and `apply` method for `CORSActionBuilder` use the static object `DefaultHttpErrorHandler` as a default value. ### Patches This is patched in Play Framework 2.8.16. The `DefaultHttpErrorHandler` object has been changed to use the prod-mode behavior, and `DevHttpErrorHandler` has been introduced for the dev-mode behavior. ### Workarounds When constructing a `CORSFilter` or `CORSActionBuilder`, ensure that a properly-configured error handler is passed. Generally this should be done by using the `HttpErrorHandler` instance provided through dependency injection or through Play's `BuiltInComponents`. Ensure that your application is not using the `DefaultHttpErrorHandler` static object in any code that may be run in production. ### References https://www.playframework.com/documentation/2.8.x/ScalaErrorHandling#Supplying-a-custom-error-handler https://www.playframework.com/documentation/2.8.x/JavaErrorHandling#Supplying-a-custom-error-handler ### For more information If you have any questions or comments about this advisory: * Open an issue in [playframework/playframework](https://github.com/playframework/playframework/) * Email us at [[email protected]](mailto:[email protected])
