This manipulation of the argument ID causes sql injection. The attack may be initiated remotely. The exploit has been published and may be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSQL injection vulnerability in itsourcecode School Management System 1.0 allows remote attackers to inject malicious SQL code via the ID parameter in /settings/index.php (Setting Handler component). The lack of proper input sanitization or parameterized queries enables attackers to manipulate database queries.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm School Management System installationLocate the web application directory or check running web services for 'school' or 'itsourcecode' identifiers. Check web server document roots for directories containing 'school' or 'school management' references.Affected if Itsourcecode School Management System is found installed or running
-
Verify vulnerable file existsCheck for the existence of /settings/index.php within the application's web directory. This file is part of the Setting Handler component.Affected if The file /settings/index.php exists in the application structure
-
Confirm version is 1.0Check application version files, headers, or any version information within the web application (often in about.php, version.txt, or admin panels). Compare against the affected version range.Affected if Installed version is exactly 1.0
-
Verify ID parameter is accessibleCheck if the /settings/index.php endpoint is accessible without authentication or if the ID parameter can be passed in requests. Attempt a simple GET request to the endpoint.Affected if The ID parameter in /settings/index.php is accessible and accepts user input
If the Itsourcecode School Management System version 1.0 is installed with the /settings/index.php file present and the ID parameter is accessible, the environment is affected by this SQL injection vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement parameterized queries/prepared statements for all database operations using the ID parameter. Apply input validation and restrict database permissions to least privilege. Apply vendor patch immediately given critical severity.
