CVE-2025-60674Public exploit

Code execution via unchecked USB serial copy

Published Nov 13, 2025 · Updated Jul 5, 2026

Stack buffer overflow in D-Link DIR-878A1 firmware FW101B04 allows physically proximate attackers to execute arbitrary code via USB. The rc binary's USB storage handler reads up to 127 bytes, then uses an unbounded sscanf conversion to copy the Serial Number value into a 64-byte stack buffer. Exploitation requires physical access or control of a USB device and can corrupt process control data for code execution on the router.
