LogicalDOC Community Edition through 9.3 Unauthenticated Upload Disk Exhaustion via UploadServlet
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
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.
