Executive Summary

[{'type': 'paragraph', 'content': "This vulnerability is an SQL injection in EdTv 2, a PHP-based web application. It occurs because the application improperly handles the 'id' parameter in the admin/edit_source endpoint, allowing attackers to inject malicious SQL code."}, {'type': 'paragraph', 'content': "Unauthenticated attackers can send specially crafted GET requests with SQL UNION statements through the 'id' parameter to execute arbitrary SQL queries on the database."}, {'type': 'paragraph', 'content': 'This can lead to extraction of sensitive database information such as schema names, user credentials, database version, and other details.'}] [1]

Detection Guidance

[{'type': 'paragraph', 'content': 'This SQL injection vulnerability can be detected by sending crafted HTTP GET requests to the vulnerable endpoint and analyzing the responses for database information leakage.'}, {'type': 'paragraph', 'content': "Specifically, you can test the 'id' parameter of the admin/edit_source endpoint by injecting SQL UNION SELECT statements to see if database schema names, user credentials, or version details are returned."}, {'type': 'paragraph', 'content': 'An example command using curl to test the vulnerability is:'}, {'type': 'list_item', 'content': 'curl "http://<target>/edtv/index.php/admin/edit_source&?id=-1 UNION SELECT 1, schema_name, 3, 4 FROM information_schema.schemata--"'}, {'type': 'paragraph', 'content': 'If the response contains database schema names or other database information, the system is vulnerable.'}] [1]
