Описание
A flaw in Node.js TLS hostname handling can cause Embedded-nul hostnames can lead to silent authority rebinding due to c-string truncation in resolver bindings.
This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
A flaw was found in Node.js. This vulnerability in the TLS (Transport Layer Security) hostname handling allows embedded null characters in hostnames. This can lead to silent authority rebinding, potentially enabling an attacker to redirect network traffic to an unintended server and disclose sensitive information.
Отчет
This Moderate impact flaw in Node.js TLS hostname handling allows for silent authority rebinding. The vulnerability arises from c-string truncation when processing embedded-nul hostnames in resolver bindings, potentially enabling an attacker to redirect TLS connections to a malicious server. Exploitation requires high attack complexity.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
