Unauthenticated crash via iProfileIdx buffer overflow
Published Sep 18, 2024 · Updated Mar 18, 2025
Buffer overflow in v2x00.cgi in DrayTek Vigor 3910 4.3.2.6 allows remote attackers to crash the router via crafted iProfileIdx input. The CGI handler fails to enforce a safe bound when processing attacker-controlled iProfileIdx data, allowing the input to overflow its destination buffer. No authentication or user interaction is required, and the documented consequence is a service-interrupting crash rather than code execution.
