CVE-2022-43548
CVE-2022-43548
In short
Node.js versions before 14.21.1, 16.18.1, 18.12.1, and 19.0.1 allow attackers to bypass security checks and perform DNS rebinding attacks, potentially leading to unauthorized command execution or access to internal services.
Technical detail
A DNS rebinding vulnerability exists due to incomplete validation of IP addresses in the IsAllowedHost check (partial fix for CVE-2022-32212). An attacker can craft malicious DNS responses to redirect requests intended for external services to internal IP addresses, bypassing host validation and enabling SSRF or command injection attacks against Node.js applications.

A OS Command Injection vulnerability exists in Node.js versions <14.21.1, <16.18.1, <18.12.1, <19.0.1 due to an insufficient IsAllowedHost check that can easily be bypassed because IsIPAddress does not properly check if an IP address is invalid before making DBS requests allowing rebinding attacks.The fix for this issue in https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-32212 was incomplete and this new CVE is to complete the fix.
