Summary

CVE-2025-68271 is a critical-severity Eval Injection (CWE-95) vulnerability. Its CVSS base score is 10.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique JavaScript (T1059.007); ranked at the 44th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

OpenC3 COSMOS, a platform for sending commands to and receiving data from embedded systems, contains a critical remote code execution vulnerability identified as CVE-2025-68271 in versions 5.0.0 through 6.10.1. The flaw affects the JSON-RPC API, where requests using the string form of certain APIs cause attacker-controlled parameter text to be parsed via the String#convert_to_value method. For array-like inputs, this parsing invokes Ruby's eval(), enabling arbitrary code execution. The issue is rated CVSS 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) and maps to CWE-95 (Improper Neutralization of Directives in Dynamically Evaluated Code).

An unauthenticated remote attacker can exploit this vulnerability by crafting a JSON-RPC request targeting the affected APIs, particularly those in the command (cmd) code path. The parsing of the command string occurs before the authorization check, allowing eval() execution even if the request later fails with a 401 Unauthorized response. Successful exploitation grants full remote code execution on the server, with high confidentiality, integrity, and availability impacts due to the changed scope.

The GitHub Security Advisory (GHSA-w757-4qv9-mghp) confirms the vulnerability and states it is fixed in OpenC3 COSMOS version 6.10.2. Security practitioners should upgrade to 6.10.2 or later and review access to JSON-RPC endpoints, restricting them to trusted networks where possible.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and code analysis can discover eval-injection flaws but does not stop their introduction.

Input validation explicitly requires neutralizing untrusted data before it reaches dynamic evaluation constructs such as eval.

Secure-development standards and tools can mandate safe coding patterns that avoid unsafe dynamic evaluation.
