FKIE_CVE-2025-68271

Vulnerability from fkie_nvd - Published: 2026-01-13 19:16 - Updated: 2026-04-15 00:35
Severity ?
10.0 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Summary
OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. From 5.0.0 to 6.10.1, OpenC3 COSMOS contains a critical remote code execution vulnerability reachable through the JSON-RPC API. When a JSON-RPC request uses the string form of certain APIs, attacker-controlled parameter text is parsed into values using String#convert_to_value. For array-like inputs, convert_to_value executes eval(). Because the cmd code path parses the command string before calling authorize(), an unauthenticated attacker can trigger Ruby code execution even though the request ultimately fails authorization (401). This vulnerability is fixed in 6.10.2.

Cuando una solicitud JSON-RPC utiliza la forma de cadena de ciertas API, el texto de par\u00e1metro controlado por el atacante se analiza en valores utilizando String#convert_to_value. Para entradas tipo array, convert_to_value ejecuta eval(). Debido a que la ruta de c\u00f3digo cmd analiza la cadena de comando antes de llamar a authorize(), un atacante no autenticado puede desencadenar la ejecuci\u00f3n de c\u00f3digo Ruby aunque la solicitud finalmente falle la autorizaci\u00f3n (401). Esta vulnerabilidad est\u00e1 corregida en 6.10.2."
