id: CVE-2019-14530

info:
  name: OpenEMR <5.0.2 - Local File Inclusion
  author: TenBird
  severity: high
  description: |
    OpenEMR before 5.0.2 is vulnerable to local file inclusion via the fileName parameter in custom/ajax_download.php. An attacker can download any file (that is readable by the web server user) from server storage. If the requested file is writable for the web server user and the directory /var/www/openemr/sites/default/documents/cqm_qrda/ exists, the file will be deleted from server.
  remediation: |
    Upgrade OpenEMR to version 5.0.2 or later to mitigate the LFI vulnerability.
