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 · unedited
A vulnerability has been found in code-projects Simple Scheduling System 1.0. This vulnerability affects unknown code of the file /schedulingsystem/addfaculty.php. Such manipulation of the argument falname leads to sql injection. The attack can be executed remotely. The exploit has been disclosed to the public 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 confidence

SQL injection vulnerability in the addfaculty.php file of Simple Scheduling System 1.0. The falname parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject arbitrary SQL commands.

MitigationReplace dynamic SQL queries with parameterized queries/prepared statements for the falname parameter in addfaculty.php. Implement input validation and use the database API's escaping functions as an additional layer of defense.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate the Simple Scheduling System installation
    Search the system for files or directories named 'schedulingsystem', 'addfaculty.php', or look for application directories containing scheduling-related PHP files.
    Affected if The application is found on the system
  2. Identify the installed version
    Check the application source code, any version file, or README for version information. The affected version is 1.0.
    Affected if The installed version is exactly 1.0 of Fabian Simple Scheduling System
  3. Verify the vulnerable file exists
    Confirm the presence of /schedulingsystem/addfaculty.php in the web root or application directory.
    Affected if The file addfaculty.php exists in the schedulingsystem directory
  4. Determine if the application is web-accessible
    Check if the web server serves the application and the /schedulingsystem/addfaculty.php endpoint is accessible over HTTP/HTTPS.
    Affected if The application is accessible via web and the addfaculty.php endpoint is reachable
  5. Check for network exposure
    Verify whether the vulnerable PHP file can be reached from external networks or the internet.
    Affected if The addfaculty.php file is exposed to untrusted networks

You are affected if Fabian Simple Scheduling System version 1.0 is installed with the addfaculty.php file accessible via the web.
