| Title | EFM IPTIME A8004T 14.18.2 Authentication Bypass & Arbitrary File Upload |
|---|
| Description | A critical security vulnerability exists in the ipTIME router firmware involving the `timepro.cgi` binary.
First, an **Authentication Bypass** vulnerability allows unauthenticated attackers to access sensitive CGI functions by utilizing the `/cgi/` URL path instead of the standard `/sess-bin/` path. This bypasses the session validation logic in the `ftext` dispatcher.
Second, an **Arbitrary File Upload** vulnerability exists in the `commit_vpncli_file_upload` function. The function fails to properly validate the file extension or file content. This allows an attacker to successfully upload an arbitrary OpenVPN configuration file (`.ovpn`) directly to the system directory `/etc/econf/vpnclient/openvpn/`.
By uploading a malicious OpenVPN configuration file containing the `script-security 2` and `up` directives, an attacker can trigger the execution of arbitrary system commands with `root` privileges when the VPN service is invoked. |
