Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')

CVE-2025-68271

High
10/10

Summary

OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. From 5.0.6 through 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.

CWE-95 - Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')

The software receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval").
