Sourcecodester Online Thesis Archiving System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Sourcecodester Online Thesis Archiving System version 1.0. The issue resides in the file '/otas/admin/curriculum/manage_curriculum.php', where user input is not properly sanitized, allowing attackers to manipulate SQL queries and potentially access or modify database information.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can interfere with the application's database queries. This could lead to unauthorized data access, data manipulation, or in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, log in with an account that has administrative privileges. Then, navigate to the 'manage curriculum' section. The vulnerability can be exploited by sending a crafted HTTP GET request to '/otas/admin/curriculum/manage_curriculum.php' with a payload that includes a SQL injection, such as '0' union select 1,2,database(),4,5,6,7. This payload exploits the 'id' parameter, injecting SQL code that the application will execute, potentially leading to database information disclosure.
