CVE-2026-72586: CWE-306: Missing Authentication for Critical Function in frangoteam FUXA
A missing authentication vulnerability in frangoteam/FUXA through 1.3.3 allows an unauthenticated remote attacker to query all historical sensor data via the DAQ_QUERY Socket.IO event. When secureEnabled=true, all other sensitive Socket.IO events (DEVICE_BROWSE, HOST_INTERFACES, DEVICE_TAGS_REQUEST, etc.) call isSocketAdminAuthorized to verify the connection token, but the DAQ_QUERY handler in server/runtime/index.js lacks this check entirely.
AI Analysis
Technical Summary
This vulnerability in frangoteam/FUXA (up to 1.3.3) is due to missing authentication on the DAQ_QUERY Socket.IO event handler. While other sensitive events require a valid connection token verified by isSocketAdminAuthorized() when secureEnabled=true, the DAQ_QUERY handler in server/runtime/index.js does not perform this check. This allows unauthenticated remote attackers to query all historical sensor data without authorization. The CVSS 3.1 score is 7.5 (high severity) with network attack vector, low attack complexity, no privileges required, no user interaction, and impact on confidentiality only.
Potential Impact
An unauthenticated remote attacker can retrieve all historical sensor data from the FUXA system, potentially exposing sensitive information. There is no impact on integrity or availability. This could lead to unauthorized disclosure of sensor data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting network access to the Socket.IO interface or disabling the DAQ_QUERY event if possible to prevent unauthorized queries.
