CVE-2017-11424

CVE-2017-11424 affects PyJWT 1.5.0 and earlier, where the invalid_strings check in HMACAlgorithm.prepare_key fails to account for all PEM public-key formats (notably PKCS1 PEM prefixed with -----BEGIN RSA PUBLIC KEY-----), enabling key confusion attacks that could let an attacker craft JWTs from ...

CVE-2017-11424

In PyJWT 1.5.0 and below the invalidstrings check in HMACAlgorithm.preparekey does not account for all PEM encoded public keys. Specifically, the PKCS1 PEM encoded format would be allowed because it is prefaced with the string -----BEGIN RSA PUBLIC KEY----- which is not accounted for. This enable...

Name of the Vulnerable Software and Affected Versions PyJWT versions 1.5.0 and below Description The issue concerns a symmetric/asymmetric key confusion attack. In PyJWT, the invalid strings check in HMACAlgorithm.prepare key does not account for all PEM encoded public keys, specifically the PKCS...

CVE-2017-11424: Undefined Security Weakness

In PyJWT 1.5.0 and below the invalidstrings check in HMACAlgorithm.preparekey does not account for all PEM encoded public keys. Specifically, the PKCS1 PEM encoded format would be allowed because it is prefaced with the string -----BEGIN RSA PUBLIC KEY----- which is not accounted for. This enable...

Invalid Curve Attack

nimbus-jose-jwt is vulnerable to invalid curve attacks. The attacks are possible because the library does not make sure that the public x and y coordinates are on the specified curve in environments where the JCE provider lacks curve validation...

Padding Oracle Attack

nimbus-jose-jwt is vulnerable to padding oracle attacks. It does not act correctly if an invalid HMAC is detected in authenticated AES-CBC decryption...

Authentication Bypass

nimbus-jose-jwt is vulnerable to authentication bypass. The bypass exists because the library ignores the checking of integer-overflow when converting length values from bytes to bits. A malicious user can shift Additional Authenticated Data AAD and ciphertext, resulting in a different plaintext...

Design/Logic Flaw

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...

Integer overflow

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...

CVE-2017-12974

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...
