Paths contain matrix variables bypass decorators

Advisory ansehen veröffentlicht 2023-07-25Lizenz: CC-BY-4.0

### Impact Spring supports [Matrix variables](https://docs.spring.io/spring-framework/reference/web/webmvc/mvc-controller/ann-methods/matrix-variables.html). When Spring integration is used, Armeria calls Spring controllers via `TomcatService` or `JettyService` with the path that may contain matrix variables. In this situation, the Armeria decorators might not invoked because of the matrix variables. Let's see the following example: ``` // Spring controller @GetMapping("/important/resources") public String important() {...} // Armeria decorator ServerBuilder sb = ... sb.decoratorUnder("/important/", authService); ``` If an attacker sends a request with `/important;a=b/resources`, the request would bypass the authrorizer ### Patches - https://github.com/line/armeria-ghsa-wvp2-9ppw-337j/commit/9b0ec3e099cc05fbff11d7f1012a1dddb0000d0c ### Workarounds Users can add decorators using regex. `e.g. "regex:^/important.*"`
