| Titre | GL-iNet GL-MT3000 4.4.5 Command Injection |
|---|
| Description | An unauthenticated command injection vulnerability exists in the /cgi-bin/glc endpoint via the ovpn-client.get_recommend_config method of the affected product. The ovpn-client.so native plugin at /usr/lib/oui-httpd/rpc/ovpn-client.so accepts a servers array. For each server entry, the hostname field is extracted, suffixed with .tcp or .udp, and passed to download_recommend_config(). This function constructs a shell command by embedding the attacker-supplied hostname into a sprintf() template and executes it via fork_exec(cmd) which calls execlp("/bin/sh", "sh", "-c", cmd, NULL). The hostname appears in all four %s positions (touch target, URL, download path, remove target), so $() command substitution fires in every position. No shell quoting or metacharacter filtering is applied to the hostname, and the /cgi-bin/glc binary calls the plugin via dlopen()/dlsym() without any authentication check, resulting in unauthenticated root command execution. |
