Authenticated router compromise via rebootTime stack overflow
Published Apr 26, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Tenda AX1806 1.0.0.1 allows remote authenticated users to corrupt router memory via reboot settings. The formSetRebootTimer handler processes the rebootTime argument at /goform/SetRebootTimer and overruns a stack buffer; the public record does not disclose the exact unsafe copy operation. Low-privileged access to the network management interface is required; successful exploitation compromises the router or interrupts service.
