Short explanation
Forge is a native TLS implementation in JavaScript. In versions prior to 1.4.1, pki.verifyCertificateChain() can permanently remove trusted CA certificates with the same subject from the CA store. This creates a persistent availability impact for applications reusing the store.
A failed chain verification can permanently remove trusted CA certificates, causing subsequent valid chains to fail and creating persistent availability issues in applications.
What should be done?
- Upgrade to version 1.4.1 or later
- Follow vendor advisories
Chain of evidence and sources
1.4.1 öncesi Forge sürümleri, pki.verifyCertificateChain() sırasında aynı konuya sahip güvenilir CA sertifikalarını CA deposundan kalıcı olarak kaldırabilir.
Başarısız bir zincir doğrulaması, daha sonra gelen geçerli zincirlerin başarısız olmasına ve kalıcı bir erişilebilirlik etkisine neden olur.
Show the technical text from the sources
Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, the affected implementation used pki.verifyCertificateChain(), pki.createCaStore(), duplicate subject names to process the relevant input or security decision. node-forge modified the CA store while trying certificates that shared a subject name during pki.verifyCertificateChain(). A failed chain verification could permanently remove trusted CA certificates from the store, causing later valid chains to fail and creating a persistent availability impact for applications that reused the store. This issue is fixed in version 1.4.1.
