Uncontrolled Recursion

  • Vulnerable module: underscore
  • Introduced through: i2c@0.2.3

Detailed paths

  • Introduced through: pi-weather-webserver@hendrik44/pi-weather-server#1031ca673d455a315758acb4b8c5ec54728e09e8 › i2c@0.2.3 › underscore@1.8.2
    Remediation: Upgrade to i2c@0.3.0.

Overview

underscore is a JavaScript's functional programming helper library.

Affected versions of this package are vulnerable to Uncontrolled Recursion through the _.flatten() or _.isEqual() functions that are used without a depth limit. An attacker can cause the application to crash or become unresponsive by supplying deeply nested data structures as input, leading to stack exhaustion.

Workaround

This vulnerability can be mitigated by enforcing a depth limit on data structures created from untrusted input (e.g., limiting nesting to 1000 levels or fewer), or by passing a finite depth limit as the second argument to the _.flatten() function.

Remediation

Upgrade underscore to version 1.13.8 or higher.

Denial of Service (DoS)

  • Vulnerable module: trim-newlines
  • Introduced through: dateformat@1.0.12

Detailed paths

  • Introduced through: pi-weather-webserver@hendrik44/pi-weather-server#1031ca673d455a315758acb4b8c5ec54728e09e8 › dateformat@1.0.12 › meow@3.7.0 › trim-newlines@1.0.0
    Remediation: Upgrade to dateformat@2.0.0.

Overview

trim-newlines is a Trim newlines from the start and/or end of a string

Affected versions of this package are vulnerable to Denial of Service (DoS) via the end() method.

Details

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

  • High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.

  • Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package

Remediation

Upgrade trim-newlines to version 3.0.1, 4.0.1 or higher.

Arbitrary Code Injection

  • Vulnerable module: underscore
  • Introduced through: i2c@0.2.3

Detailed paths

  • Introduced through: pi-weather-webserver@hendrik44/pi-weather-server#1031ca673d455a315758acb4b8c5ec54728e09e8 › i2c@0.2.3 › underscore@1.8.2
    Remediation: Upgrade to i2c@0.3.0.

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.
