Path Traversal occurrences in Seeddms
SeedDMS 6.0.17 and 5.1.24 are vulnerable to Directory Traversal. The "Remove file" functionality inside the "Log files management" menu does not sanitize user input allowing attackers with admin privileges to delete arbitrary files on the remote system. (2022-06-06, CVE-2022-28478)
A directory traversal flaw in SeedDMS (formerly LetoDMS and MyDMS) before 5.1.8 allows an authenticated attacker to write to (or potentially delete) arbitrary files via a .. (dot dot) in the "op/op.UploadChunks.php" "qquuid" parameter. NOTE: this can be leveraged to execute arbitrary code by using CVE-2018-12940. (2018-07-31, CVE-2018-12939)
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).
