CVE-2022-43548: high-severity vulnerability in NodeJS Node
Published · Updated
E-mail alert when it lands in KEV, gets a public PoC or its score goes up.
No sign of exploitation. No public exploitation artifact known so far.
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.
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.
In the same product, most dangerous first.
