Published Aug 5, 2026 · Updated Aug 10, 2026 · Assigned by TuranSec

Description

Domoticz's MochadTCP::MatchLine handler for MOCHAD_RFSEC messages (hardware/MochadTCP.cpp) copies network-received data from the up-to-1028-byte m_mochadbuffer into a fixed 50-byte stack buffer tempRFSECbuf using strcpy with no length check, across three separate code branches (DS10A/KR10A/MS10A device types).
