Summary
Domoticz's MochadTCP::MatchLine handler for MOCHAD_RFSEC messages 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).
Risk Assessment
This could lead to a stack-based buffer overflow, potentially allowing remote code execution or crashing the Domoticz system.
Recommendation
Update Domoticz to a patched version or use safe string copy functions with length checks.
Other vulnerabilities in Domoticz
See all- CVE-2026-11425Medium
Domoticz versions prior to 2026.3 contain a stored cross-site scripting vulnerability in the mobile dashboard, allowing authenticated attackers to inject arbitrary HTML and JavaScript by updating Text or Alert subtype device values through the API. The mobile dashboard renders data via ng-bind-html without proper escaping, enabling malicious payloads to execute in an administrator's browser.
- CVE-2026-1001Medium
Domoticz versions prior to 2026.1 contain a stored cross-site scripting vulnerability in the Add Hardware and rename device functionality. An authenticated administrator can inject malicious code via crafted names containing script or HTML markup, which is stored and executed in the browsers of other users viewing the affected page.
