| Название | FAST FAC1900R 20190827_2.0.2 Stack-based Buffer Overflow |
|---|
| Описание | A stack-based buffer overflow vulnerability exists in the copy_msg_element function within the firmware's devdiscover service (at offset 0x4049C464). This function calls memcpy when copying message element data, but fails to perform an upper-bound check on a user-controllable length field originating from network packets. A specially crafted UDP request can trigger this vulnerability. |
