AI risk analysis

Summary
The flaw involves an insecure use of strcpy without length checking, leading to potential stack buffer overflow when processing MOCHAD_RFSEC messages in Domoticz.
Exploitability
Exploitation requires specific device types and large input sizes, making it moderately difficult but feasible with the right conditions.
Blast radius
If exploited, this could lead to remote code execution or service disruption affecting devices using these specific hardware types.
Prioritized remediation
Update Domoticz to a patched version that addresses the buffer overflow vulnerability in MochadTCP::MatchLine handler.

NVD 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).
