The bug stems from an unsafe use of the C library function strcpy, which can overflow a buffer when a payload longer than the allocated space is received.

Exploitation requires sending a crafted HTTP request to the vulnerable endpoint without authentication. While the description does not confirm the exact impact, the overflow could plausibly lead to arbitrary code execution, which would compromise confidentiality, integrity, and availability of the device."}}}}, "created": "2026-03-09T10:03:40.595678+00:00", "updated": "2026-04-17T12:15:18.160350+00:00", "vendors": ["utt", "utt$PRODUCT$hiper_810g"]}
