CVE-2017-12972 WRITEUP HIGH WRITEUP
Connect2id Nimbus Jose+jwt < 4.39 - Data Authenticity Bypass
In Nimbus JOSE+JWT before 4.39, there is no integer-overflow check when converting length values from bytes to bits, which allows attackers to conduct HMAC bypass attacks by shifting Additional Authenticated Data (AAD) and ciphertext so that different plaintext is obtained for the same HMAC.
CVSS 7.5
CVE-2017-12973 WRITEUP LOW WRITEUP
Nimbus JOSE+JWT <4.39 - Info Disclosure
Nimbus JOSE+JWT before 4.39 proceeds improperly after detection of an invalid HMAC in authenticated AES-CBC decryption, which allows attackers to conduct a padding oracle attack.
CVSS 3.1
CVE-2017-12974 WRITEUP HIGH WRITEUP
Connect2id Nimbus Jose+jwt < 4.36 - Signature Verification Bypass
Nimbus JOSE+JWT before 4.36 proceeds with ECKey construction without ensuring that the public x and y coordinates are on the specified curve, which allows attackers to conduct an Invalid Curve Attack in environments where the JCE provider lacks the applicable curve validation.
CVSS 7.5
