id: CVE-2018-12909

info:
  name: Webgrind <= 1.5 - Local File Inclusion
  author: DhiyaneshDk
  severity: high
  description: |
    Webgrind 1.5 relies on user input to display a file, which lets anyone view files from the local filesystem (that the webserver user has access to) via an index.php?op=fileviewer&file= URI
  impact: |
    Unauthenticated attackers can read arbitrary files including sensitive configuration files, database credentials, and system files that the web server has access to.
  remediation: |
    Upgrade Webgrind to a version higher than 1.5 or apply the necessary patches provided by the vendor.
