CVE-2022-50932Public exploitNetwork attack vector

Unauthenticated file disclosure via null-byte path traversal

Published Jan 13, 2026 · Updated Jan 13, 2026

Path traversal in KYOCERA Command Center RX on ECOSYS M2035dn devices allows remote attackers to read arbitrary system files without authentication. The embedded web server passes a null-byte-terminated traversal path from /js/ to file lookup, causing the appended .jpg suffix to be ignored and the resolved path to escape the web root. Network access to the device is sufficient; demonstrated requests return /etc/passwd and /etc/shadow, exposing account and password-hash data without write or service-interruption impact.
