What is CVE-2025-57293?

A vulnerability in the COMFAST CF-XR11 router allows an attacker to perform command injection through the multi_pppoe API. This occurs because the phy_interface parameter is not properly sanitized, enabling unauthorized command execution when an attacker sends a crafted POST request to the device. Specifically, if the action parameter is set to 'one_click_redial', the unsafe phy_interface is passed to a system() call, which can result in the execution of arbitrary commands, leading to potential unauthorized access and full compromise of the device.
