XSS URL Analysis and SQL Injection Workflow
- This article delves into Cross-Site Scripting (XSS) and SQL Injection vulnerabilities, explaining their workflows with examples, code samples, and flow diagrams.
- XSS allows attackers to inject malicious scripts into web pages, leading to session hijacking or data theft; types include Stored, Reflected, and DOM-based XSS.
- XSS exploitation involves crafting a malicious URL, sending it to the victim, executing the script, and performing malicious actions.
- SQL Injection manipulation of SQL queries can lead to data leaks or database compromise; types include In-Band, Blind, and Out-of-Band SQL Injection.
- An SQL Injection example showcases bypassing authentication by injecting ' OR 1=1 --.
- SQL Injection exploitation involves crafting malicious input, executing the SQL query, and gaining control of the database.
- Commonly used XSS payloads include alerts, stealing cookies, hijacking sessions, and keyloggers.
- Common SQL injection payloads include authentication bypass, union-based, error-based, and blind SQL Injections.
- Regular testing with tools like OWASP ZAP or Burp Suite is recommended to prevent vulnerabilities and protect against attackers.
- By understanding these vulnerabilities and implementing proper security measures, the risk of attacks can be significantly reduced.
