CVE-2016-8218

CVE-2016-8218 affects Cloud Foundry’s routing-release (versions prior to 0.142.0) and cf-release (203–231). The issue is incomplete validation in JSON Web Token (JWT) libraries, enabling unprivileged attackers to impersonate other users to the routing API. Remediation: upgrade routing-release to ...

Timing Attack

github.com/dgrijalva/jwt-go is vulnerable to timing attacks. This vulnerability is caused because the hashes are not compared in constant time, allowing malicious users to guess the valid hashes are based on the time that a comparison takes...

Invalid Curve Attack

node-jose, nimbus-jose-jwt and jose4j are vulnerable to invalid curve attacks. These attacks are possible when using key agreement with Elliptic Curve Diffie-Hellman Ephemeral Static ECDH-ES, allowing attackers to recover the private secret key...

CVE-2016-7037

The CVE concerns Malcolm Fell jwt (before 1.0.3). The verify function in Encryption/Symmetric.php does not use a timing-safe hash comparison, allowing an attacker to spoof signatures via timing attacks. Impact is signature forgery; remediation is upgrading to version 1.0.3 or later (as per refere...

Denial Of Service (DoS)

json-jwt is vulnerable to denial of service DoS attacks. A malicious attacker can cause a denial of service when decoding the jwt-json signatures. This is unsafe because the tokens are stored as symbols that allocates memory to a string but is not removed by the garbage collection after being use...

Timing Attack

json-jwt is vulnerable to timing attacks. The library is vulnerable because they do not compare signatures in constant-time, which allows malicious users to use the timing of the request to progressively identify a valid signatures...

CVE-2016-8218: Unauthenticated JWT signing algorithm in routing | Cloud Foundry

CVE-2016-8218: Unauthenticated JWT signing algorithm in routing Critical Vendor Cloud Foundry Foundation Versions Affected routing-release versions prior to 0.142.0 cf-release versions 203 to 231 Description Incomplete validation logic in JSON Web Token JWT libraries can allow unprivileged...

Forgeable Public/Private Tokens

Overview Affected versions of the jws package allow users to select what algorithm the server will use to verify a provided JWT. A malicious actor can use this behaviour to arbitrarily modify the contents of a JWT while still passing verification. For the common use case of the JWT as a bearer...

Forgeable Public/Private Tokens

Overview Affected versions of the jwt-simple package allow users to select what algorithm the server will use to verify a provided JWT. A malicious actor can use this behaviour to arbitrarily modify the contents of a JWT while still passing verification. For the common use case of the JWT, the en...

Verification Bypass

Overview Versions 4.2.1 and earlier of jsonwebtoken are affected by a verification bypass vulnerability. This is a result of weak validation of the JWT algorithm type, occuring when an attacker is allowed to arbitrarily specify the JWT algorithm. Recommendation Update to version 4.2.2 or later...

CVE-2015-2964

CVE-2015-2964 affects namshi/jose (PHP JWT library). A vulnerability in processing JWT headers allows bypass of signature verification, enabling specially crafted tokens to be treated as valid data. Public sources indicate the library did not properly enforce signature checks (e.g., issues with t...
