The vulnerability CVE-2025-14286 is an information disclosure flaw in the Tenda AC9 router’s web management interface. It resides in an unspecified function of the `Configuration File Handler` component, specifically within the `/cgi-bin/DownloadCfg.jpg` CGI endpoint. This endpoint is designed to handle configuration files but contains improper access controls. An attacker can exploit this by sending a crafted HTTP request to this accessible URL without requiring any authentication or user interaction. The request manipulates the endpoint’s functionality to force the disclosure of the router’s configuration file. This attack can be launched remotely over the network. A successful exploit results in the router sending its sensitive configuration data to the attacker. This leaked information typically includes critical network details such as administrative passwords, Wi-Fi credentials (SSID and pre-shared keys), and other network topology settings. The public disclosure of the exploit details increases the likelihood of attack attempts, posing a direct risk to network confidentiality.
