GHSA-3227-r97m-8j95

Summary: Relative Path Traversal in afire serve_static

Details: ### Impact This vulnerability effects the built-in afire serve_static extension allowing paths containing `//....` to bypass the previous path sanitation and request files in higher directories that should not be accessible. ### Patches The issue has been fixed in [afire 1.1.0](https://crates.io/crates/afire/1.1.0). If you can, just update to the newest version of afire. ### Workarounds If you can't update afire you can simply disallow paths containing `/..` with the following middleware. Make sure this is the last middleware added to the server so it runs first, stopping the bad requests. ```rust use afire::prelude::*; struct PathTraversalFix; impl Middleware for PathTraversalFix { fn pre(&self, req: Request) -> MiddleRequest { if req.path.replace("\\", "/").contains("/..") { return MiddleRequest::Send( Response::new() .status(400) .text("Paths containing `..` are not allowed"), ); } MiddleRequest::Continue } } ``` ```rust let mut server = Server::new(host, port); PathTraversalFix.attach(&mut server); ``` ### References You can read about the new changes to afire in 1.1.0 [here](https://connorcode.com/writing/afire/update-3) ### For more information If you have any questions or comments about this advisory you can email me or message me on discord.
