Omschrijving
Node.js heeft meerdere kwetsbaarheden verholpen in versies 22.x, 24.x en 26.x, waaronder in de HTTP/2-implementatie, HTTPS-servermodule, TLS-handling en proxy error handling.
Verschillende kwetsbaarheden in Node.js kunnen leiden tot informatielekken, geheugenfouten en serveruitval. Vooral omgevingen met HTTP/2, HTTPS en TLS worden geraakt.
- Proxy-authenticatie: uitlekken van inloggegevens via foutmeldingen.
- HTTP/2: buffer overflow, geheugenlekken, overbelasting en servercrashes.
- Bestandsbewaking: omzeilen van toegangsbeperkingen op macOS en Windows.
- zlib: dienstverstoring door foutieve verwerking van datastromen.
- HTTPS-server: geheugenfouten waardoor gevoelige gegevens, waaronder TLS-privésleutels, kunnen uitlekken.
- TLS 1.2: omzeilen van authenticatie met clientcertificaten.
- TLS-sessies: onjuist hergebruik van sessies met verschillende certificaatinstellingen.
Oplossingen
Node.js heeft updates uitgebracht in versies 22.23.0, 24.17.0, 24.18.0 en 26.x om deze kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
