  • RS256 Token Validation & Decoding using Public Key Not Working

    RS256 Token Validation & Decoding using Public Key Not Working "ValueError: Could not deserialize key data."

    I'm trying to validate Google's ID Tokens for user authentication on a web app. The id token can be decoded fine if I disable verification, but won't verify when I pass it the RSA256 Public Key. The Public Key in question is Base64urlUInt-Encoded (RFC 7518 Specification).

      }
    

    According to the Specification I linked above, the "n" parameter is the Modulus, and the "e" parameter is the exponent. I've tried absolutely every combination of decoding these to common Base64 format, but no matter what I do, pyJWT doesn't like it.

    Expected Result

    Reproduction Steps

    import jwt
    
    IDjwt = <my id_token here>  # Decoding this with verify=False works correctly, so the problem isn't with the ID Token

    #Convert to Base64 (replace '-', '_' with '+', '/', respectively, and pad with '=' to make multiple of 4)
    GoogPubKey = GoogPubKey.replace(b'-', b'+')
    GoogPubKey = GoogPubKey.replace(b'_', b'/')
    GoogPubKey += b'=='
    len(GoogPubKey) % 4  # 0
    GoogPubKey = b'-----BEGIN PUBLIC KEY-----\n' + GoogPubKey + b'\n-----END PUBLIC KEY-----'
    
    decoded = jwt.decode(IDjwt, GoogPubKey, algorithms='RS256')
    

    Again, I've tried over a dozen different ways of using this RSA Public Key Google supplies, but nothing works (Using Base64url like they provide, using or not using the 'BEGIN PUBLIC KEY' prefix/suffix, type bytes or str, adding the "AQAB" prefix in multiple places, nothing works)

    Any help would be greatly appreciated!! Thank you

    According to the JSON Web Algorithms Draft, section 3.4 the ECDSA signature should be serialized by concatenating the R and S values.

    The code was using ecdsa.util.sigencode_der, that encodes the signature using the DER serialization format, instead of using ecdsa.util.sigencode_string, that does exactly what the draft asks.

  • Invalid validation of audience claim

    Invalid validation of audience claim

    The spec at http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#audDef states:

    The aud (audience) claim identifies the recipients that the JWT is intended for. Each principal intended to process the JWT MUST identify itself with a value in the audience claim. If the principal processing the claim does not identify itself with a value in the aud claim when this claim is present, then the JWT MUST be rejected.

    As I understand it, Pyjwt doesn't seem to implement this requirement correctly. Basically it reverses the checks. Let me explain.

    Pyjwt only checks the audience claim when an audience=... arg was specified to decode(), meaning that any audience claim in the JWT is blindly ignored if no such arg was passed. This results in the JWT bein accepted, instead of being rejected. (Security problem!)

    Furthermore, the decode(audience=...) arg allows both a string and a list of strings, but the audience claim in the JWT payload is always assumed to be a single string, which is against the spec:

    In the general case, the aud value is an array of case-sensitive strings, each containing a StringOrURI value. In the special case when the JWT has one audience, the aud value MAY be a single case-sensitive string containing a StringOrURI value. The interpretation of audience values is generally application specific. Use of this claim is OPTIONAL.

    Offending code:

        if audience is not None:
            if isinstance(audience, list):
                audiences = audience
            else:
                audiences = [audience]
    
            if payload.get('aud') not in audiences:
                raise InvalidAudience('Invalid audience')
    

    Hopefully you understand what I meant when I said pyjwt "reverses" the checks.

    Let me know your thoughts; I can come up with a PR when we agree on the correct approach and understanding of the spec.

  • How do I detect an invalid token?

    How do I detect an invalid token?

    Suppose a hacker tries to pass a token to my server, that did not originate from my server. How do I detect when this happens?

    I am guessing that If the token was not something generated and signed with my key, then one of two things will happen:

    1. pyjwt will throw a JSONDecode error. jwt.decode won't even be able to decode the token, as the decryption algorithm will produce garbledygook.
    2. jwt.decode returns an object, but it won't have any of the expected keys (because, again, garbledygook) so any attempt to access an expected key will result in a KeyError.

    Hey folks,

    You probably have already looked into this, but since I couldn't find any closed issues on this I decided to create this as more of an FYI.

    cryptography package was affected by CVE-2022-3602 and CVE-2022-3786 and they have addressed the issue in the v38.0.3 release.

    Since pyjwt is not pointing to a specific version of cryptography, installing pyjwt[crypto] pulls in the latest version of cryptography. So I think the risk here is minimal. Just wanted to let you know anyway. Do you think it is worth updating the minimum version of cryptography in dependencies? https://github.com/jpadilla/pyjwt/blob/300348f7bc4a520448b8fbefa525c9434e82141d/setup.cfg#L48

    When using PyJWKClient to access a jwks server behind a firewall, I've run into problems with my request being denied due to the default Python-urllib/3.9 user agent.

    Would the maintainers entertain allowing users to specify a custom headers dictionary when creating the pyJWKClient that would automatically be set on fetch requests to retrieve the JWK? By allowing a generic header dictionary to be included, you could solve not only the user agent difficulties I've run into, but other use cases as well.

    very unhelpfull / missleading error messages on get_signing_key_from_jwt

    Hello,

    I spend a few hours today for a bug that shouldn't have been there. I set up my python application where I recieve a jwt token from oauth-proxy, validate, decode and echo the contents. Running locally, everything went perfect. Running in a container I got the message "The JWK Set did not contain any usable keys". I checked, oauth configs, credentials, my code, put a few hours into trying to debug the python code while running in podman.

    Then after a few hours my colleague helped and ran the project on his machine. He got the same error. So what does his machine has not, that mine has? Dependencies.

    After another hour of debuging, we found out, that my jwt token is encoded with RSA. For pyjwt to decode the key we need to use RSA. To use RSA the cryptography is nessecary. I got this installed in my global dependencies and forgot to use an env.

    The thing is: Alls this could have been prevented, if the raised error message would be "found RSA - cannot decode because dependency cryptography is missing"

    Instead the error handling is as follows:

    and has_crypto comes from algorithms.py

    try:
        import cryptography.exceptions
    ....
    except ModuleNotFoundError:
        has_crypto = False
    

    As summary: You iterate through every key, looking if there is an algorithm, find that a dependecie is missing and skip this key, and buring the error message. Afterwards the length of the list of keys is 0 - you get the message of no usable keys and are none the wiser, why this is the case. please rework you try catch error flow, so that a developer knows when a dependency is missing for the current key!

    Support for JWKs containing ECDSA keys

    Drop support for Python 2

    Require cryptography >= 3

    Drop support for PyCrypto and ECDSA

    We've kept this around for a long time, mostly for environments that didn't allow installing cryptography.

    Drop CLI

    Dropped the included cli entry point.

    Improve typings

    We no longer need to use mypy Python 2 compatibility mode (comments)

    Add support for Ed25519 / EdDSA

    Security

    A security researcher has notified JSON Web Token library maintainers about a number of vulnerabilities allowing attackers to bypass the verification step. Read more about some of this issues here.

    This release fixes the vulnerabilities reported, continue reading for details.

    None algorithm

    Applies if you

    • rely on and do not validate the alg field in the token header.
    • implement the "none" algorithm.

    Impact

    Attackers can craft a malicious token containing an arbitrary payload that passes the verification step.

    Exploit

    Create a token with the header {"typ":"JWT","alg":"none"}. Include any payload. Do not include a signature (i.e. the token should end with a period). Note: some implementations include some basic but insufficient checking for a missing signature -- some minor fiddling may be required to produce an exploit.

    Asymmetric key of a token signed with a symmetric key

    Applies if you

    • rely on and do not validate the alg field in the token header.
    • implement at least one of the HMAC algorithms and at least one of the asymmetric algorithms (e.g. HS256 and RS256).

    Impact

    If the system is expecting a token signed with one of the asymmetric algorithms, an attacker can bypass the verification step by knowing only the public key.

    Exploit

    Create an HS256 token. Generate the HMAC signature using the literal bytes of the public key file (often in the PEM format). This will confuse the implementation into interpreting the public key file as an HMAC key.

    This release was possible thanks to the awesome @mark-adams.

    • [Enhancement] Allow datetime.timedelta for leeway argument. #56

    Pending Deprecation

    The following exceptions have been marked for deprecation in favor of a renamed one to follow a better convention and will be removed in the next major version release.

    • ExpiredSignature will be deprecated in favor of ExpiredSignatureError.
    • InvalidAudience will be deprecated in favor of InvalidAudienceError.
    • InvalidIssuer will be deprecated in favor of InvalidIssuerError.

    Thanks to @mark-adams and @wbolster for all the work and feedback that went into this release.
