CVE-2025-26198 is a SQL injection vulnerability in CloudClassroom-PHP-Project v1.0 affecting the loginlinkadmin.php component. The application does not properly sanitize or parameterize user-supplied input from the admin login form before incorporating it into backend SQL queries. According to the provided content, the issue is exploitable through the username field by supplying crafted SQL syntax such as ' OR '1'='1. This can alter the intended query logic, bypass authentication checks, and grant unauthorized access to the administrative interface. Because the flaw exists in an authentication workflow, successful exploitation may also expose sensitive backend data accessible to the admin context.

This repository demonstrates a proof-of-concept (POC) exploit for CVE-2025-26198, a SQL injection vulnerability in CloudClassroom-PHP-Project v1.0. The repository contains six files: a Python exploit script (exploit.py), a vulnerable PHP login handler (app/loginlinkadmin.php), a web login page (app/index.html), a SQL initialization script (app/sql/init.sql), a Docker Compose configuration (docker-compose.yml), and an empty README.md. The exploit.py script targets the loginlinkadmin.php endpoint, sending a crafted POST request with a SQL injection payload in the username field to bypass authentication and gain admin access. The PHP code in loginlinkadmin.php is intentionally vulnerable, concatenating user input directly into an SQL query without sanitization. The repository is structured as a self-contained educational lab, with Docker Compose used to deploy the vulnerable application and its MySQL backend. The exploit demonstrates a network-based attack vector and provides a clear example of how SQL injection can compromise web application authentication.
