Performing a manipulation of the argument ID results in sql injection. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks.

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 SourceCodester Class and Exam Timetabling System 1.0's edit_exam2.php file allows remote attackers to manipulate the ID parameter to inject arbitrary SQL queries. The vulnerability is remotely exploitable and public exploits are available.

MitigationReplace dynamic SQL queries with parameterized queries (prepared statements) in edit_exam2.php, validating and sanitizing all user input before using it in database operations.

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. Confirm the application is SourceCodester Class and Exam Timetabling System
    Inspect the application banner, footer, or source code for the product name. Check the web root directory for the typical file structure of this PHP application.
    Affected if The installed application is SourceCodester Class and Exam Timetabling System
  2. Verify the version is 1.0
    Look for a version identifier in the application source files, such as in a config file, readme, or the main index page. Compare against the affected version range.
    Affected if The version is 1.0 or falls within any unpatched version range of this system
  3. Locate edit_exam2.php in the web directory
    Search the web root for the file edit_exam2.php. Common paths include the admin folder or the root directory of the application.
    Affected if The file edit_exam2.php exists and is web-accessible
  4. Inspect the ID parameter handling in edit_exam2.php
    Open edit_exam2.php and examine how the ID parameter is handled. Look for direct insertion of $_GET['id'] or $_POST['id'] into SQL queries without using prepared statements, parameter binding, or input sanitization.
    Affected if The ID parameter is used directly in SQL queries without parameterized queries or input validation
  5. Confirm database connectivity is enabled
    Verify the application has a functional database connection by checking the configuration file for database credentials and connection status.
    Affected if The application connects to a MySQL or other SQL database that can be targeted by the injected queries

The system is affected if it runs SourceCodester Class and Exam Timetabling System version 1.0, has the edit_exam2.php file accessible, and that file uses the ID parameter directly in SQL queries without prepared statements.
