tiêu đềFast FAC1203R Gigabit Edition 20200116_2.0.4 Stack-based Buffer Overflow
Mô tảA stack-based buffer overflow vulnerability exists in the copy_msg_element function within the firmware's device discovery service. This function calls a memcpy/memmove-like routine when copying message element data, but fails to perform an upper-bound check on a user-controllable length field originating from UDP packets. A specially crafted UDP request to port 5001 can trigger this vulnerability.
