path library/setup/rpc.php↗

• → Monitor HTTP requests to `library/setup/rpc.php` containing the `objectname` parameter with path traversal sequences (e.g., `../`) or PHP code injection patterns (e.g., `();`). ↗
• → Detect RCE attempts via the `objectname` parameter containing PHP function call syntax such as semicolons and parentheses (e.g., `Xmenu();phpinfo();die`). ↗
• → Look for null-byte (`%00`) injection in the `objectname` parameter, used to truncate the appended `.php` extension during LFI exploitation. ↗

• · The exploit PoC uses `site.com` as a placeholder; the actual vulnerable path `library/setup/rpc.php` is relative to the Gravity GTD installation root and may vary by deployment. ↗
• · Affects Gravity GTD version 0.4.5 and earlier; versions beyond 0.4.5 are not confirmed vulnerable. ↗
