Node.js Multiple Vulnerabilities (August 2021 Security Releases)

critical Nessus Plugin ID 154231


Node.js - JavaScript run-time environment is affected by multiple vulnerabilities.


The version of Node.js installed on the remote host is prior to 12.22.5 or 14.17.5 or 16.6.2. It is, therefore, affected by multiple vulnerabilities including the following:

- A remote command execution vulnerability exists in Node.js due to insufficient validation of untypical characters in domain names. An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands. (CVE-2021-22931)

- A security bypass vulnerability exists in the HTTPS API of Node.js. An unauthenticated, remote attacker can exploit this to cause connections to servers with an expired certificate to be accepted. (CVE-2021-22939)

- A use after free vulnerability exists in Node.js. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2021-22940)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to Node.js version 12.22.5 / 14.17.5 / 16.6.2 or later.
