Cells Path Traversal

Directory traversal in the Copy, Move, and Delete features in Pydio Cells 2.2.9 allows remote authenticated users to enumerate personal files (or Cells files belonging to any user) via the nodes parameter (for Copy and Move) or via the Path parameter (for Delete). (2021-09-30, CVE-2021-41324)

Directory traversal in the Compress feature in Pydio Cells 2.2.9 allows remote authenticated users to overwrite personal files, or Cells files belonging to any user, via the format parameter. (2021-09-30, CVE-2021-41323)

Pydio Cells 2.0.4 allows an authenticated user to write or overwrite existing files in another user’s personal and cells folders (repositories) by uploading a custom generated ZIP file and leveraging the file extraction feature present in the web application. The extracted files will be placed in the targeted user folders. (2020-06-04, CVE-2020-12851)

Pydio Cells before 1.5.0 fails to neutralize '../' elements, allowing an attacker with minimum privilege to Upload files to, and Delete files/folders from, an unprivileged directory, leading to Privilege escalation. (2019-06-20, CVE-2019-12901)

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).
