Exploitation Summary
EIP tracks 2 public exploits for CVE-2018-1000125. PoCs published by dawetmaster, andikahilmy.
AI-analyzed exploit summary This repository contains a vulnerable version of the Prime JWT library (1.2.1) that demonstrates CVE-2018-1000125, an authentication bypass vulnerability due to improper handling of the 'none' algorithm in JWT verification. The code includes functional JWT encoding/decoding logic, including support for HMAC and RSA signing, but lacks proper validation for unsecured tokens.
Description
inversoft prime-jwt version prior to version 1.3.0 or prior to commit 0d94dcef0133d699f21d217e922564adbb83a227 contains an input validation vulnerability in JWTDecoder.decode that can result in a JWT that is decoded and thus implicitly validated even if it lacks a valid signature. This attack appear to be exploitable via an attacker crafting a token with a valid header and body and then requests it to be validated. This vulnerability appears to have been fixed in 1.3.0 and later or after commit 0d94dcef0133d699f21d217e922564adbb83a227.
