CVE-2023-45282: Prototype Pollution in NASA Open MCT

Background

NASA Open MCT (aka openmct) is an open-source software framework for building web-based mission control applications. It provides a customizable user interface and a set of APIs for developers to create and manage telemetry displays, historical data views, and other features. However, a vulnerability has been discovered in Open MCT that allows for prototype pollution, which can be exploited through an import action.

Vulnerability Detail

The prototype pollution vulnerability in Open MCT can lead to the modification or addition of properties to existing objects. This can result in unexpected behavior or security issues, such as remote code execution or privilege escalation. The vulnerability arises from improper handling of user-supplied input during the import action, allowing an attacker to inject malicious data that pollutes the prototype chain of objects.

Workaround

As a temporary workaround, developers can disable the import action or implement input validation and sanitization measures to mitigate the risk of prototype pollution. Here is an example of input validation using JavaScript:

function validateImportData(data) {
  if (typeof data === 'object' && !Array.isArray(data)) {
    // Perform additional validation checks
    return true;
  }
  return false;
}

By validating the imported data to ensure it is an object and not an array, the risk of prototype pollution can be reduced.

Conclusion

The prototype pollution vulnerability in NASA Open MCT can have serious security implications. It is crucial to update to the latest version and implement proper input validation to mitigate the risk. For further assistance or support in addressing this vulnerability, please contact DevNack.com.
