CVE-2026-76584Public exploitNetwork attack vector

Code execution via Currenttime overflow

Published Aug 19, 2026 · Updated Aug 20, 2026

Stack-based buffer overflow in the alphapd set_time.cgi handler in TRENDnet TV-IP751WIC 11.03.03 allows attackers to crash the device via Currenttime. The published CVE names the Currenttime parameter, and the referenced GitHub research says alphapd reads that HTTP value and routes it into unsafe processing that corrupts memory, but the exact overflowing function has not been publicly identified. Reachability is network-based, but published sources disagree on the gate: the CNA scored PR:L, while the public PoC claims the CGI endpoint is exposed during initial setup, so exposed camera web interfaces warrant urgent triage.
