# CodeFever: path traversal in document controller lets remote users read files

CodeFever, a PHP project management tool, has a path traversal flaw in the _detail function of application/controllers/doc.php where the uri_string argument is not sanitized. A remote attacker can use it to reach files outside the intended directory on the server.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the deployed CodeFever checkout includes commit `e4433eee96883a222403854e8ac38b3146774a07` (for example `git branch --contains e4433eee96883a222403854e8ac38b3146774a07` in the install directory)
- Look at application/controllers/doc.php in the install and see whether the _detail function still passes uri_string through without sanitizing
- unknown for versions: the product uses a rolling release model and the sources give no affected version numbers

## Fix

- Apply patch commit `e4433eee96883a222403854e8ac38b3146774a07` to the CodeFever install, or update to a release that contains it
- unknown for a specific version number: the sources state no fixed release
- Restrict the web server's access to files outside the application directory until patched

The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The identifier of the patch is e4433eee96883a222403854e8ac38b3146774a07.
