Detailsinfo

A vulnerability has been found in frangoteam FUXA up to 1.3.1 and classified as critical. Affected by this vulnerability is an unknown code block of the file server/runtime/index.js of the component Socket IO Handler. The manipulation of the argument property.address/endpoint with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, the DEVICE_WEBAPI_REQUEST and DEVICE_PROPERTY Socket.IO handlers in server/runtime/index.js omit isSocketWriteAuthorized and accept attacker-controlled property.address or endpoint connection data. A remote unauthenticated attacker can make server/runtime/devices/httprequest/index.js call axios.get against arbitrary HTTP or HTTPS destinations, connect to reachable OPC UA or ODBC services, and receive results through the corresponding Socket.IO event. This read SSRF oracle can expose cloud instance metadata, internal administrative services, industrial endpoints, and ODBC data reachable from the FUXA host, including when secureEnabled is true. This issue is fixed in version 1.3.2.
