CVE-2025-22469Network attack vector

Unauthenticated command execution via undisclosed input handling

Published Aug 6, 2025 · Updated Aug 6, 2025

OS command injection in SATO CL4/6NX Plus and CL4/6NX-J Plus firmware before 1.15.5-r1 allows remote attackers to execute commands. Neither SATO nor JPCERT/CC has disclosed the vulnerable handler or the untrusted input passed into an operating-system command. No authentication or user interaction is required over the network, and successful commands run under a non-administrative account that can read, alter, or interrupt printer functions.
