| Title | FAST FAC1200R V5.0_20201119_1.0.2 Stack-based Buffer Overflow |
|---|
| Description | A stack-based buffer overflow vulnerability exists in the devdiscover service path of the FAC1200R firmware. When the service handles UDP packets on port 5001, a type-1 advertisement packet can reach parse_advertisement_frame, then parse_msg_element, and finally a copy-like function at 0x80444928. |
