Summary

Magistrala's Rules Engine allows authenticated users to create rules with embedded Go or Lua scripts executed server-side. The Lua engine performs no input validation and preloads dangerous libraries enabling arbitrary code execution, DB access, file I/O, SSRF, and path traversal.

Risk Assessment

An attacker can execute arbitrary code on the server, access the database, read files, or perform SSRF attacks, potentially leading to full system compromise.

Recommendation

Restrict rule creation access, implement script validation, and remove dangerous libraries from the Lua runtime environment.

Other vulnerabilities in Magistrala

CVE-2026-71276High
Magistrala (formerly Mainflux)'s message-readers API reads a value from the HTTP query string (readers/api/http/transport.go) with no validation and interpolates it directly into raw SQL queries via fmt.Sprintf in both the PostgreSQL reader (readers/postgres/messages.go: ) and the TimescaleDB reader (readers/timescale/messages.go, same pattern), enabling SQL injection by any authenticated user able to query channel messages.

Original NVD description (English source)

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).
