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.
