JWT_AUTH_COOKIE Vulnerable To CSRF Attacks

django-rest-framework-jst creates a JWT token, JWTAUTHCOOKIE, which is vulnerable to cross-site request forgery CSRF attacks. When using django.middleware.csrf.CsrfViewMiddleware the Django framework will typically generate a secured CSRF token and ensure that it is validated upon submission of a...

Incorrect Access Control vulnerability in src/Firebase/Auth/IdTokenVerifier.php does not verify for token signature that can result in JWT with any email address and user ID could be forged from an actual token, or from thin air.

Bugfixes Fixed a security issue discovered by @hernandev that enabled an attacker to impersonate any registered user in a Firebase application...

Timing Attack

emarref/jwt is vulnerable to a timing attack. It is possible because the verify function in Symmetric.php does not compare hashes in constant time, allowing malicious users to guess valid hashes based on the time that a comparison takes...

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...

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...
