CVE-2022-44748Network attack vector

Arbitrary file overwrite via workflow archive traversal

Published Nov 24, 2022 · Updated Apr 25, 2025

Path traversal in KNIME Server 4.3.0 and later affected releases allows remote authenticated users to overwrite files via workflow upload. The ZIP extraction routines accept traversal paths in workflow entries and write them outside the intended extraction directory. Exploitation requires upload permission and knowledge of target paths; writes are limited to locations writable by the server process and can corrupt files or enable code execution when replaced executables later run.
