4) Reliance on Reverse DNS Resolution for a Security-Critical Action

EUVDB-ID: #VU69354

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-43548

CWE-ID: CWE-350 - Reliance on Reverse DNS Resolution for a Security-Critical Action

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DNS rebinding attacks.

The vulnerability exists due to improper validation of octal IP address within the Node.js rebinding protector for --inspec. A remote attacker can resolve the invalid octal address via DNS. When combined with an active --inspect session, such as when using VSCode, an attacker can perform DNS rebinding and execute arbitrary code in client's browser.

Mitigation

Install updates from vendor's website.
