CVE-2023-22322

Local file disclosure via external entity resolution

Published Jan 30, 2023 · Updated Mar 27, 2025

XXE in OMRON CX-Motion Pro 1.4.6.013 and earlier allows attackers to read local files through crafted project files. The project-file XML parser resolves attacker-defined external entities instead of prohibiting access to external resources. Exploitation requires a user to open the crafted file, and the reported consequence is disclosure of files readable by that user.
