Assigner: MITRE

Description
A stack buffer overflow vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin in the rc binary's USB storage handling module. The vulnerability 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. An attacker with physical access or control over a USB device can exploit this vulnerability to potentially execute arbitrary code on the device.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a stack buffer overflow in the D-Link DIR-878A1 router firmware, specifically in the USB storage handling module of the rc binary. It happens because the "Serial Number" field from a USB device is read into a 64-byte stack buffer using sscanf, but fgets reads up to 127 bytes, which can overflow the buffer. An attacker with physical access or control over a USB device can exploit this to potentially execute arbitrary code on the device.


How can this vulnerability impact me? :

If exploited, this vulnerability can allow an attacker with physical access or control over a USB device to execute arbitrary code on the affected router. This could lead to unauthorized control over the device, potentially compromising network security and functionality.
