CVE-2023-26759Public exploitNetwork attack vector

Authenticated command execution via exposed service calls

Published Feb 27, 2023 · Updated Mar 11, 2025

OS command injection in Sme.UP ERP TOKYO V6R1M220406 allows remote authenticated users to execute operating system commands. The Loocup component accepts crafted calls to the /debug and /XMLService endpoints that pass attacker-controlled function input to backend system-command execution. A valid connection code or AS/400 password is required, and commands run with the application process's privileges, enabling shell access or malware execution.
