Improper Cryptographic Algorithm

jose4j is vulnerable to Improper Cryptographic Algorithm. The vulnerability exists due to the way RSA15 and RSAOAEP is implemented, allowing an attacker to decrypt RSA15 or RSAOAEP encrypted ciphertexts, and in addition, it may be feasible to sign with affected keys...

Chosen Ciphertext Attack in Jose4j

Summary RSA15 in jose4j is susceptible to chosen ciphertext attacks. The attack allows to decrypt RSA15 or RSAOAEP encrypted ciphertexts. It may be feasible to sign with affected keys. Severity Moderate - exploiting this ciphertext attack could result in the ability to decrypt RSA15 or RSAOAEP...
