Arbitrary Code Injection

  • Vulnerable module: underscore
  • Introduced through: smtp-connection@2.8.0

Detailed paths

  • Introduced through: nodemailer-smtp-transport@2.6.0 › smtp-connection@2.8.0 › httpntlm@1.6.1 › underscore@1.7.0

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.
