Description A stack buffer overflow issue exists in the USB storage handling module of the D-Link DIR-878A1 router firmware. The problem occurs when the “Serial Number” field from a USB device is read into a 64-byte stack buffer using sscanf, while fgets can read up to 127 bytes, leading to a stack overflow. An attacker with physical access or control over a USB device could potentially execute arbitrary code on the device.
