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 was found in code-projects Exam Form Submission 1.0. It has been declared as critical. This vulnerability affects unknown code of the file /admin/delete_s3.php. The manipulation of the argument ID leads to sql injection. The attack can be initiated 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 Exam Form Submission 1.0 allows remote attackers to inject malicious SQL queries via the ID parameter in /admin/delete_s3.php. The lack of parameterized queries or input sanitization enables arbitrary database manipulation.

MitigationReplace dynamic SQL concatenation with prepared statements/parameterized queries in delete_s3.php and implement proper input validation on the ID parameter before executing any 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 Exam Form Submission 1.0 is installed
    Locate the application files and check the version identifier in the source code, typically found in a version file, README, or the main index.php header comment
    Affected if The installed version is Exam Form Submission 1.0
  2. Verify delete_s3.php exists
    Check for the presence of the file /admin/delete_s3.php in the web application directory
    Affected if The file /admin/delete_s3.php exists on the server
  3. Inspect the ID parameter handling in delete_s3.php
    Open delete_s3.php and examine how the ID parameter is processed - look for SQL queries that concatenate the ID parameter directly into the query string without using prepared statements or parameter binding
    Affected if The ID parameter is used in a SQL query without parameterized queries or input sanitization
  4. Check web server access to admin directory
    Verify that the /admin/ directory is accessible via the web server (not restricted by authentication or network controls)
    Affected if The delete_s3.php endpoint is reachable over the network without authentication

You are affected if Exam Form Submission version 1.0 is installed, the file delete_s3.php exists, and the ID parameter in that file is handled with dynamic SQL concatenation rather than prepared statements.
