CVE-2021-45253 is a critical-severity flaw (CVSS 9.8) affecting simple cold storage managment system. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The id parameter in view_storage.php from Simple Cold Storage Management System 1.0 appears to be vulnerable to SQL injection attacks. A payload injects a SQL sub-query that calls MySQL's load_file function with a UNC file path that references a URL on an external domain. The application interacted with that domain, indicating that the injected SQL query was executed.
