LogicalDOC Community Edition through 9.3 contains an unauthenticated file upload vulnerability in the UploadServlet that allows remote attackers to write files to disk without a session. Attackers can repeatedly send multipart requests with unlimited file parts to /upload, persisting files in uncleaned temporary directories and exhausting server disk space.
