Short explanation
Prior to version 1.4.1, digitalbazaar forge accepts a PKCS#12 MAC or password-based encryption iteration count of zero or less, leading to an integrity bypass vulnerability.
This vulnerability allows attackers to bypass password-based integrity checks and manipulate crafted PKCS#12 inputs, posing a high risk to data integrity.
What should be done?
- Upgrade to version 1.4.1
- Follow the vendor advisory
Chain of evidence and sources
digitalbazaar forge 1.4.1 öncesi sürümler, PKCS#12 MAC veya parola tabanlı şifreleme yineleme sayısının sıfır veya daha az olmasını kabul eder.
pki.pbe.generatePkcs12Key() fonksiyonu parola ve tuzdan bağımsız sabit bir anahtar döndürür.
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, node-forge accepted a PKCS#12 MAC or PKCS#12 password-based encryption iteration count of zero or less. pki.pbe.generatePkcs12Key() then returned a constant key independent of the password and salt, allowing crafted PKCS#12 input processed by forge.pkcs12.pkcs12FromAsn1() to bypass password-based integrity checks. Predictable encryption keys and IVs also affected PKCS#12 PBE using pbeWithSHAAnd3-KeyTripleDES-CBC or pbewithSHAAnd40BitRC2-CBC, including shrouded key bags, encrypted SafeContents, and PKCS#8 ENCRYPTED PRIVATE KEY input processed independently by forge.pki.decryptPrivateKeyInfo(). PBES2/PBKDF2-encrypted content is unaffected. This issue is fixed in version 1.4.1.
