CVE-2024-28102

JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an attacker can cause a denial of service attack by passing in a malicious JWE Token with a high compression ratio. When the server processes this token, it will consume a lot of memory and...

CVE-2024-28102 JWCrypto vulnerable to JWT bomb Attack in `deserialize` function

JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an attacker can cause a denial of service attack by passing in a malicious JWE Token with a high compression ratio. When the server processes this token, it will consume a lot of memory and...

CVE-2024-28102

Summary: CVE-2024-28102 affects the Python JWCrypto/JWCrypto implementation. Before 1.5.6, processing a malicious JWE token with a high compression ratio can cause a DoS by consuming excessive memory and CPU time; the vulnerability stems from the token deserialization path. Affected component: py...

CVE-2024-21664

A null pointer dereference vulnerability was found in the jwx/jws Go module. This issue arises when invoking "jws.Parse" with a JSON serialized payload containing a present signature field while the protected field is absentm, which may cause a system crash or initiate a denial of service DOS...

Null pointer dereference

jwx is a Go module implementing various JWx JWA/JWE/JWK/JWS/JWT, otherwise known as JOSE technologies. Calling jws.Parse with a JSON serialized payload where the signature field is present while protected is absent can lead to a nil pointer dereference. The vulnerability can be used to crash/DOS ...

CVE-2024-21664 Parsing JSON serialized payload without protected field can lead to segfault

jwx is a Go module implementing various JWx JWA/JWE/JWK/JWS/JWT, otherwise known as JOSE technologies. Calling jws.Parse with a JSON serialized payload where the signature field is present while protected is absent can lead to a nil pointer dereference. The vulnerability can be used to crash/DOS ...

Parsing JSON serialized payload without protected field can lead to segfault

Summary Calling jws.Parse with a JSON serialized payload where the signature field is present while protected is absent can lead to a nil pointer dereference. Details This seems to also affect other functions that calls Parse internally, like jws.Verify. My understanding of these functions from t...

CVE-2023-49290

lestrrat-go/jwx is a Go module implementing various JWx JWA/JWE/JWK/JWS/JWT, otherwise known as JOSE technologies. A p2c parameter set too high in JWE's algorithm PBES2- could lead to a denial of service. The JWE key management algorithms based on PBKDF2 require a JOSE Header Parameter called p2c...

CVE-2023-23928

reason-jose is a JOSE implementation in ReasonML and OCaml.Jose.Jws.validate does not check HS256 signatures. This allows tampering of JWS header and payload data if the service does not perform additional checks. Such tampering could expose applications using reason-jose to authorization bypass...

Authorization Bypass

jwcrypto is vulnerable to authorization bypass. The vulnerability is due to JWT auto-detecting the token type; under certain circumstances, it's possible to substitute a signed JWS token with a JWE token encrypted with the public key used for signature validation...

jwcrypto token substitution can lead to authentication bypass

The JWT code can auto-detect the type of token being provided, and this can lead the application to incorrect conclusions about the trustworthiness of the token. Quoting the private disclosure we received : "Under certain circumstances, it is possible to substitute a .. signed JWS with a JWE that...
