Insufficient Entropy in parsel

All versions of parsel use an insecure key derivation function. The package runs keys of arbitrary lengths through one round of SHA256 hashing for key stretching. This allows for the use of keys of insufficient entropy with inappropriate key stretching. Recommendation The package is deprecated an...

GHSA-WQGX-4Q47-J2W5 Insecure Cryptography Algorithm in parsel

All versions of parsel use an insecure cryptography algorithm. The package uses aes-256-cbc without integrity checks, which renders the ciphertext vulnerable to bit-flipping attacks. Recommendation The package is deprecated and will not be updated. Consider using an alternative package...

Bit-Flipping Attack

Amendment This was deemed not a vulnerability. Overview parsel is a gem to encrypt and decrypt data with a given key. Affected versions of this package are vulnerable to Bit-Flipping Attack via the ciphertext function. AES-256-CBC, the construct used in parsel.rb, has no integrity check i.e., the...

Insecure Encryption

Overview parsel is a gem to encrypt and decrypt data with a given key. Affected versions of this package are vulnerable to Insecure Encryption. In cases where an initialisation vector is not supplied to the encrypt or decrypt call in parsel.rb, the initialisation vector used by the library is set...
