CVE-2026-2944Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized DevId

Published Feb 22, 2026 · Updated Feb 22, 2026

OS command injection in TOSEI Online Store Management System 1.01 allows remote attackers to execute commands through an HTTP POST request. The system call in /cgi-bin/monitor.php incorporates the unsanitized DevId value into a shell command, allowing semicolons to append attacker-supplied commands. No authentication or user interaction is required, and commands run under the web server account, allowing data access, modification, or service interruption.
