CVE-2025-8271
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 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 confidenceSQL 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.

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.
-
Confirm Exam Form Submission 1.0 is installedLocate 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 commentAffected if The installed version is Exam Form Submission 1.0
-
Verify delete_s3.php existsCheck for the presence of the file /admin/delete_s3.php in the web application directoryAffected if The file /admin/delete_s3.php exists on the server
-
Inspect the ID parameter handling in delete_s3.phpOpen 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 bindingAffected if The ID parameter is used in a SQL query without parameterized queries or input sanitization
-
Check web server access to admin directoryVerify 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.
Generated from the published advisory. Verify against your own configuration.
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 concatenation with prepared statements/parameterized queries in delete_s3.php and implement proper input validation on the ID parameter before executing any database operations.
