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 · moderate confidence

A SQL injection vulnerability exists in SourceCodester Simple Online Book Store System where the 'bookisbn' parameter in /obs/bookPerPub.php is not properly sanitized, allowing remote attackers to inject malicious SQL queries.

MitigationReplace dynamic SQL queries with parameterized queries/prepared statements, implement strict input validation on the bookisbn parameter, and conduct a broader code audit for similar injection vulnerabilities.

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 Online Book Store System installation
    Search your web server directories for the 'obs' folder or the file 'bookPerPub.php'. Common paths include /var/www/html/, /htdocs/, or C:\inetpub\wwwroot\. Use 'find /path -name bookPerPub.php' or search your file system for 'bookPerPub.php'.
    Affected if The file /obs/bookPerPub.php exists on your server and is part of a Simple Online Book Store System installation
  2. Verify the vulnerable parameter is accessible
    Check if the file is directly accessible via HTTP/HTTPS. Attempt to access: http://yourdomain.com/obs/bookPerPub.php or https://yourdomain.com/obs/bookPerPub.php in a browser or via curl. Look for a form or page that accepts a 'bookisbn' parameter.
    Affected if The page loads and accepts a 'bookisbn' parameter, typically via GET or POST request
  3. Confirm the application is running
    Review your web server logs (access logs) for requests to /obs/bookPerPub.php. Check if the application is actively running by visiting the main page of the Book Store System.
    Affected if The application is live and serving requests to the vulnerable endpoint
  4. Identify the application version
    Examine the source code of bookPerPub.php for version comments, check for a README file, version.php, or any metadata file within the Simple Online Book Store System installation folder.
    Affected if Any version of Simple Online Book Store System is installed, since all versions are affected according to the CVE details
  5. Test for SQL injection vulnerability (optional, requires authorization)
    If you have authorization, send a test request with a non-malicious payload in the bookisbn parameter such as 'test' or a single quote to observe if SQL errors are returned. Example: curl 'http://yourdomain.com/obs/bookPerPub.php?bookisbn='
    Affected if The application returns SQL error messages or behaves unexpectedly when special characters are passed to the bookisbn parameter

You are affected if the Simple Online Book Store System is installed and the file /obs/bookPerPub.php is accessible with the bookisbn parameter in use.
