CVE-2021-22884

Disclosure Date: March 03, 2021 •
CVE-2021-22884 CVSS v3 Base Score: 7.5
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to DNS rebinding attacks as the whitelist includes “localhost6”. When “localhost6” is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim’s DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain. As long as the attacker uses the “localhost6” domain, they can still apply the attack described in CVE-2018-7160.
