Received Received - Intake

Unauthenticated JavaScript Code Execution in rust-iot-platform

Publication date: 2026-08-05

Last updated on: 2026-08-10

Assigner: TuranSec

Description

rust-iot-platform allows creating a "calc rule" via POST /calc-rule/create (api/src/controller/calc_rule_router.rs) containing an arbitrary field. This route does not take the AuthToken request guard used elsewhere in the application, making it reachable without authentication.

Attack-Flow Graph

Executive Summary

This vulnerability in rust-iot-platform allows unauthenticated attackers to create a calc rule with an arbitrary script field via an unprotected POST endpoint. The script is later executed without sandboxing, enabling arbitrary JavaScript code execution on the server.

Detection Guidance

Check for unauthorized POST requests to /calc-rule/create without authentication tokens. Inspect server logs for suspicious calc rule creations or executions. Look for unexpected JavaScript execution in server processes.

Impact Analysis

An attacker could exploit this to run malicious code on the server, potentially stealing data, installing malware, disrupting services, or gaining full control of the system. The high CVSS score indicates severe impact.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection and security, such as GDPR's integrity principle or HIPAA's security rule, due to unauthorized code execution and potential data breaches.

Mitigation Strategies

Immediately restrict access to the /calc-rule/create endpoint to require valid AuthToken. Disable or remove the calc rule functionality if not needed. Update the application to enforce authentication and sandbox JavaScript execution.
