A critical authentication bypass vulnerability has been discovered in one of the biggest identity-as-a-service platform Auth0 that could have allowed a malicious attacker to access any portal or application, which are using Auth0 service for authentication. Auth0 offers token-based authentication solutions for a number of platforms including the ability to integrate social media authentication into an application. With over 2000 enterprise customers and managing 42 million logins every day and billions of login per month, Auth0 is one of the biggest identity platforms. While pentesting an application back in September 2017, researchers from security firm Cinta Infinita discovered a flaw ( CVE-2018-6873 ) in Auth0's Legacy Lock API , which resides due to improper validation of the JSON Web Tokens (JWT) audience parameter.
