Kali Linux: Scan Vulnerability using Grabber (en)

Grabber is a web application scanner. It primarily detects various types of vulnerabilities on your site. Grabber is simple, not fast but portable and very easy to adapt. This software is designed to scan small websites like personal sites, forums, etc. Applications that are really not large: it would take too long and flood your network.

Features:

• Cross-Site Scripting (XSS)
• SQL Injection (there is also a special module for Blind SQL Injection)
• File Inclusion
• Backup file check
• Simple AJAX check (parses each JavaScript and obtains URLs and tries to get their parameters)
• Hybrid analysis/Crystal ball testing for PHP applications using PHP-SAT
• JavaScript source code analyzer: Evaluation of the quality/correctness of JavaScript with JavaScript Lint
• Creates [session_id, time(t)] files for further stats analysis.

Grabber Usage Example

Spider web application to depth 2 (–spider 2), check for SQLi (--sql), XSS (--xss), and blind SQLi (--bsql) attack for URL (--url http://192.168.0.100/DVWA-1.9/):

grabber --spider 2 --sql --xss --bsql --url http://192.168.0.100/DVWA-1.9/
