CVE-2018-25149Public exploitNetwork attack vector

Administrative changes via unchecked web requests

Published Dec 24, 2025 · Updated Dec 24, 2025

Cross-site request forgery in Microhard Systems IPn4G 1.1.0 build 1098 allows remote attackers to alter settings via crafted pages. The web interface accepts state-changing POST requests to /cgi-bin/webif/system-acl.sh without validating request origin or an anti-CSRF token. A logged-in administrator must load the malicious page; the forged request can change the administrator password, add privileged users, or alter device settings.
