CVE-2025-10547 is a high-severity remote code execution vulnerability in DrayTek Vigor routers running DrayOS. The flaw resides in the HTTP CGI request-argument processing used by the web management interface and is caused by use of an uninitialized variable. Available reporting indicates the bug involves an uninitialized stack value that can lead to invalid memory handling, including use of free() on an attacker-influenced memory location, resulting in memory corruption. A remote attacker can trigger the condition by sending specially crafted HTTP or HTTPS requests to the router’s WebUI or related management interface components, without authentication. Successful exploitation can crash the device and, in exploitable conditions, achieve arbitrary code execution on the appliance, including root-level compromise.
