CVE-2026-0732Public exploitNetwork attack vector

Authenticated command execution via path concatenation

Published Jan 8, 2026 · Updated Jan 8, 2026

Command injection in D-Link DI-8200G 17.12.20A1 allows remote authenticated users to execute OS commands via a crafted path parameter. The /upgrade_filter.asp handler concatenates the path and time form values into a system command without neutralizing shell metacharacters. Access to the management interface and a valid session are required; successful exploitation runs attacker-chosen commands with the web service's device privileges.
