Title

Magistrala IoT Platform - Unrestricted Go/Lua Script Execution in Rules Engine

Summary

Magistrala's Rules Engine allows authenticated users to create rules with embedded Go or Lua scripts executed server-side when IoT messages arrive. The Lua script engine (re/lua.go) performs no input validation at all and preloads dangerous libraries: db (arbitrary database access), ioutil (file I/O), an HTTP client (SSRF), and filepath (traversal).

Severity

8.8 (High)

GHSA-VQ5V-M87M-6PQM

Vulnerability from github – Published: 2026-08-05 12:31 – Updated: 2026-08-05 12:31

Details

Magistrala's Rules Engine allows authenticated users to create rules with embedded Go or Lua scripts executed server-side when IoT messages arrive. The Go script engine (re/golang.go) runs scripts through the Yaegi interpreter with stdlib.Symbols, exposing the full Go standard library (including os and net/http) with validation limited to a regex blocking goroutines and panic() calls; dangerous functions such as os.ReadFile, os.WriteFile, os.Remove, and os.Environ remain fully accessible. The Lua script engine (re/lua.go) performs no input validation at all and preloads dangerous libraries: db (arbitrary database access), ioutil (file I/O), an HTTP client (SSRF), and filepath (traversal). An authenticated low-privileged user can achieve arbitrary file read/write, environment variable leakage, database access, and SSRF against internal microservices.

Severity

8.8 (High)

Vulnerability from csaf_redhat - Published: 2026-08-25 14:28 - Updated: 2026-09-24 11:07

Summary

Red Hat Security Advisory: Red Hat OpenShift API for Data Protection

Severity

Important

Scope

19 vulnerabilities in this advisory, including CVE-2026-71235.

CVE-2026-71235

A flaw was found in Magistrala's Rules Engine. An authenticated low-privileged user can exploit this vulnerability by creating rules with embedded Go or Lua scripts. These scripts are executed server-side without sufficient validation, allowing for arbitrary file read and write operations, access to internal databases, and Server-Side Request Forgery (SSRF) against internal microservices. This could lead to significant data compromise and unauthorized system access.

8.8 (High)
