CVE-2025-4010Public exploit

Root command execution via CGI eval

Published Jun 2, 2025 · Updated Jun 2, 2025

OS command injection in all NetComm NTC-6200 firmware and NWL-222 before 2.1.21.1 allows remote authenticated users to execute commands as root. Six CGI shell scripts under /www/cgi-bin parse QUERY_STRING into variables and pass attacker-controlled text to eval without neutralizing shell syntax. Access to the web interface and valid credentials is required, although hardcoded default accounts can satisfy that gate; exploitation grants unrestricted root command execution.
