CVE-2022-36509Public exploit

Arbitrary command execution via filter bypass

Published Aug 25, 2022 · Updated Jun 17, 2025

Command injection in H3C GR3200 firmware MiniGR1B0V100R014 and earlier allows local users to execute arbitrary OS commands. The DelL2tpLNSList handler formats the param request value with snprintf, passes it to system, and permits its character filter to be bypassed with shell command substitution. A request to /goform/aspForm with a management-session cookie reaches the handler, and injected commands execute with the router process's privileges.
