Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA flaw has been found in code-projects Simple Scheduling System 1.0. This affects an unknown part of the file /schedulingsystem/addsubject.php. This manipulation of the argument subcode causes sql injection. Remote exploitation of the attack is possible. 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.

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.
-
Locate the Simple Scheduling System installationSearch the web server document root for the Fabian Simple Scheduling System application files, specifically looking for addsubject.php or other PHP files belonging to this applicationAffected if The application files are present on the server
-
Identify the installed versionExamine the application source code, any README files, or version headers for version information. Compare against the affected version 1.0Affected if The installed version is 1.0
-
Verify addsubject.php is web-accessibleCheck that addsubject.php exists in a web-accessible directory and can be reached via HTTP/HTTPS requestsAffected if The vulnerable file is publicly accessible via the web
-
Inspect addsubject.php for SQL injection vulnerabilityExamine the source code of addsubject.php and look for how the subcode parameter is handled in database queries, specifically checking for lack of prepared statements or parameterized queriesAffected if The subcode parameter is used in dynamic SQL queries without proper sanitization or prepared statements
If Fabian Simple Scheduling System version 1.0 is installed with addsubject.php accessible and the subcode parameter is processed in SQL queries without prepared statements or input validation, the environment is affected.

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 dataReplace dynamic SQL queries with prepared statements/parameterized queries in addsubject.php, implement strict input validation on the subcode parameter, and apply vendor security patches if available.
