Vulnerability from github – Published: 2022-05-24 19:18 – Updated: 2022-05-24 19:18

Details

The CivetWeb web library does not validate uploaded filepaths when running on an OS other than Windows, when using the built-in HTTP form-based file upload mechanism, via the mg_handle_form_request API. Web applications that use the file upload form handler, and use parts of the user-controlled filename in the output path, are susceptible to directory traversal

Severity

9.8 (Critical)
