Summary
A stack buffer overflow vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin in the USB storage handling module. The issue occurs when the "Serial Number" field from a USB device is read via sscanf into a 64-byte stack buffer, while fgets reads up to 127 bytes, causing a stack overflow.
Risk Assessment
An attacker with physical access or control over a connected USB device can exploit this vulnerability to potentially execute arbitrary code on the device, which could lead to full compromise of the router.
Recommendation
Immediately update the D-Link DIR-878A1 router firmware to the latest available version if a patch has been released. In the meantime, restrict physical access to the device and avoid connecting untrusted USB devices.
