Detailsinfo

A vulnerability classified as problematic was found in Node.js (unknown version). Affected by this vulnerability is an unknown code block of the component Socket Close Handler. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. The summary by CVE is:

A memory leak could occur when a remote peer abruptly closes the socket without sending a GOAWAY notification. Additionally, if an invalid header was detected by nghttp2, causing the connection to be terminated by the peer, the same leak was triggered. This flaw could lead to increased memory consumption and potential denial of service under certain conditions. This vulnerability affects HTTP/2 Server users on Node.js v18.x, v20.x, v22.x and v23.x.

This vulnerability is known as CVE-2025-23085 since 01/10/2025. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1499 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 214404 (Node.js 18.x < 18.20.6 / 20.x < 20.18.2 / 22.x < 22.13.1 / 23.x < 23.6.1 Multiple Vulnerabilities (Tuesday, January 21, 2025 Security Releases).), which helps to determine the existence of the flaw in a target environment.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (214404) and CERT Bund (WID-SEC-2025-0156). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
