Technical ContextAI · show details

This vulnerability is classified under CWE-121. 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. Affected products include: Dlink Dir-878 Firmware. Version information: up to 127.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Stack-based Buffer Overflow HIGH

A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
