Local mail disclosure via permissive temporary files
Published Jan 6, 2023 · Updated Apr 10, 2025
Temporary file exposure in Apache James Server 3.7.2 and earlier allows local users to read private mail data during SMTP or IMAP APPEND processing. The SMTP message buffers and IMAP APPEND paths use File.createTempFile, which can apply permissive host defaults to files holding messages in transit. Exploitation requires local host access during file lifetime and provides message disclosure without reported modification or service interruption.
