Auth tag forgery vulnerability with AES-GCM encrypted JWT

Ruby's OpenSSL bindings do not check the length of the supplied authentication tag when decrypting an authenticated encryption mode such as AES-GCM, leaving this up to the authors of a gem/app to implement for properly validating the message. json-jwt was not checking for the authentication tag...

REST API Penetration Testing: Astra

REST API penetration testing is complex due to continuous changes in existing APIs and newly added APIs. Astra can be used by security engineers or developers as an integral part of their process, so they can detect and patch vulnerabilities early during development cycle. Astra can automatically...

Timing Attack

authentikat-jwt is vulnerable to timing attacks. The vulnerability exists as the insecure function, contentEquals, used to compare between two given signatures in verify, was not constant, and results in the leaking of sensitive information from the signature...

Input validation

A time-sensitive equality check on the JWT signature in the JsonWebToken.validate method in main/scala/authentikat/jwt/JsonWebToken.scala in authentikat-jwt aka com.jason-goodwin/authentikat-jwt version 0.4.5 and earlier allows the supplier of a JWT token to guess bit after bit of the signature b...

CVE-2017-18239

A time-sensitive equality check on the JWT signature in the JsonWebToken.validate method in main/scala/authentikat/jwt/JsonWebToken.scala in authentikat-jwt aka com.jason-goodwin/authentikat-jwt version 0.4.5 and earlier allows the supplier of a JWT token to guess bit after bit of the signature b...

CVE-2017-18239

The CVE-2017-18239 entry concerns the authentikat-jwt library (Scala) in main/scala/authentikat/jwt/JsonWebToken.scala. A time-sensitive equality check in JsonWebToken.validate for the JWT signature (versions 0.4.5 and earlier) can allow an attacker to recover the signature bit-by-bit by issuing ...
