Path Traversal occurrences in Discord-recon
Discord-Recon is a bot for the Discord chat service. In versions of Discord-Recon 0.0.3 and prior, a remote attacker is able to read local files from the server that can disclose important information. As a workaround, a bot maintainer can locate the file `app.py` and add `.replace('..', '')` into the `Path` variable inside of the `recon` function. The vulnerability is patched in version 0.0.4. (2021-04-22, CVE-2021-29466)
Why Path Traversal can be dangerous
Relative Path Confusion means that your web server is configured to serve responses to ambiguous URLs. This configuration can possibly cause confusion about the correct relative path for the URL. It is also an issue of resources, such as images, styles etc., which are specified in the response using relative path, not the absolute URL.
If the web browser permits to parse "cross-content" response, the attacker may be able to fool the web browser into interpreting HTML into other content types, which can then lead to a cross site scripting attack (link do XSS).
