Denial of Service (DoS)

  • Vulnerable module: axios
  • Introduced through: axios@0.16.2

Detailed paths

  • Introduced through: resource-downloader@0.5.3 › axios@0.16.2
    Remediation: Upgrade to axios@0.18.1.

Overview

axios is a promise based HTTP client for the browser and node.js.

Affected versions of this package are vulnerable to Denial of Service (DoS) due to content continuing to be accepted from requests after maxContentLength is exceeded.

PoC

require('axios').get(
  'https://upload.wikimedia.org/wikipedia/commons/f/fe/A_Different_Slant_on_Carina.jpg',
  { maxContentLength: 2000 }
)
  .then(d => console.log('done'))
  .catch(e => console.log(e.toString()))

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 axios to version 0.18.1 or higher.

Remediation

Upgrade axios to version 0.21.1 or higher.
