Schedule disclosure via world-readable temporary files
Published Nov 25, 2022 · Updated Apr 23, 2025
Information disclosure in MPXJ before 10.14.1 allows local users to read project schedule data from temporary files. InputStreamHelper.writeStreamToTempFile and FileHelper.createTempDir use File.createTempFile, which creates world-readable files on affected Unix-like hosts. Exploitation requires a separate local account and precise timing while MPXJ processes a schedule that uses a temporary file or directory; Windows and macOS are not affected.
