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...

GHSA-GWP4-MCV4-W95J 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...

CVE-2022-36083

JOSE is "JSON Web Almost Everything" - JWA, JWS, JWE, JWT, JWK, JWKS with no dependencies using runtime's native crypto in Node.js, Browser, Cloudflare Workers, Electron, and Deno. The PBKDF2-based JWE key management algorithms expect a JOSE Header Parameter named p2c PBES2 Count, which determine...

CVE-2022-36083

CVE-2022-36083 affects the Node.js jose module (JWA/JWS/JWE/JWT/JWK/JWKS) used in multiple runtimes. The issue arises from a JOSE Header parameter p2c (PBES2 count) that controls PBKDF2 iterations for deriving the CEK. A malicious untrusted JWE could specify an extremely high p2c, causing CPU-bou...

Design/Logic Flaw

The package jsrsasign before 10.5.25 are vulnerable to Improper Verification of Cryptographic Signature when JWS or JWT signature with non Base64URL encoding special characters or number escaped characters may be validated as valid by mistake. Workaround: Validate JWS or JWT signature if it has...

CVE-2022-25898

The CVE-2022-25898 entry concerns the jsrsasign library (pre-10.5.25) where JWS/JWT signatures with non Base64URL-encoded or escaped characters may be validated as valid. Affected component: jsrsasign; root cause: improper verification of cryptographic signatures. Impact (per sources): potential ...

Insecure Signature Verification

jsrsasign is vulnerable to insecure signature verification. The vulnerability exists because the library does not properly validate the JWS or JWT signature with non-Base64URL encoding special characters or number escaped characters such as !@$% or \11...

JWS and JWT signature validation vulnerability with special characters

Impact Jsrsasign supports JWSJSON Web Signatures and JWTJSON Web Token validation. However JWS or JWT signature with non Base64URL encoding special characters or number escaped characters may be validated as valid by mistake. For example, even if a string of non Base64URL encoding characters such...
