CVE-2023-5327

File disclosure via full parameter traversal

Published Oct 1, 2023 · Updated Sep 20, 2024

Path traversal in /rest/dir/ on SATO CL4NX-J Plus 1.13.2-u455_r2 allows remote authenticated users to read files. The endpoint resolves the attacker-controlled full parameter without restricting traversal outside the intended directory. Access requires reachability to the printer WebConfig service on the local network, and the published impact is limited to file disclosure.
