Description
A vulnerability was found in EFM iptime A6004MX 14.18.2. Affected is the function commit_vpncli_file_upload of the file /cgi/timepro.cgi. The manipulation results in unrestricted upload. The attack may be performed from remote. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
A critical vulnerability has been identified in the EFM iptime A6004MX router running firmware version 14.18.2. This vulnerability arises from an authentication bypass that allows unauthenticated attackers to access sensitive CGI functions via the '/cgi/' URL path, circumventing standard session validation. Additionally, the 'commit_vpncli_file_upload' function in '/cgi/timepro.cgi' introduces an arbitrary file upload vulnerability. It fails to properly validate file extensions or contents, enabling attackers to upload malicious OpenVPN configuration files (.ovpn) to the '/etc/econf/vpnclient/openvpn/' directory. These files can execute arbitrary commands with root privileges when the VPN service is activated.
