CVE-2024-2850Public exploitNetwork attack vector

Authenticated service crash via unchecked URLs copy

Published Mar 24, 2024 · Updated Aug 1, 2024

Heap buffer overflow in Tenda AC15 15.03.05.18 allows remote authenticated users to crash the router's HTTP service via crafted urls input. The saveParentControlInfo handler copies the urls field between heap-allocated buffers without enforcing the destination length. Access to the router control panel is required, and public reproduction establishes a service crash but not code execution through this field.
