| Title | GL-iNet GL-MT3000 4.4.5 Command Injection |
|---|
| Description | An unauthenticated command injection vulnerability exists in the /cgi-bin/glc endpoint via the s2s.enable_echo_server method of the affected product. The s2s.so native plugin at /usr/lib/oui-httpd/rpc/s2s.so validates the port parameter only through atoi() for numeric range checking (1-65534), then passes the original unsanitized string to snprintf() + system(). The /cgi-bin/glc binary loads the plugin via dlopen()/dlsym() without any authentication check, resulting in root command execution without authentication. |
