Summary
A POST request sent to a specific webserver endpoint can be used to write to arbitrary file locations. The endpoint accepts the filename parameter in the Content-Disposition header without verification. This can be used to cause a denial of service by overwriting system files, or remote-code-execution by overwriting shell-scripts which execution can be triggered through other means.
