Path Traversal occurrences in Git-server
The resolveRepositoryPath function doesn't properly validate user input and a malicious user may traverse to any valid Git repository outside the repoRoot. This issue may lead to unauthorized access of private Git repositories as long as the malicious user knows or brute-forces the location of the repository. (2020-08-14, CVE-2020-9708)
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).
