Security Bulletin

This security bulletin contains one medium risk vulnerability.

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

EUVDB-ID: #VU69354

Risk: Medium

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

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 repository.
