Exploring Common SQL Injection Vulnerabilities in Web Applications: A Bug Bounty Perspective
As a bug bounty hunter or security researcher, understanding potential vulnerabilities in web applications is crucial. One of the most common and dangerous vulnerabilities is SQL Injection (SQLi). In this blog post, we'll explore some common endpoints that are often susceptible to SQLi attacks across various web technologies.
SQL Injection vulnerabilities occur when user input is not properly sanitized before being used in SQL queries. This can allow attackers to manipulate the query and potentially access, modify, or delete sensitive data.
Here are some common endpoints that are frequently vulnerable to SQLi attacks, categorized by file extension:
1. PHP (.php) Applications:
- index.php?category=
- product.php?id=
- news.php?article_id=
- user.php?username=
- login.php?username=&password=
- search.php?q=
- blog.php?post_id=
- forum.php?thread_id=
- profile.php?user_id=
- admin.php?username=&password=
2. ASP (.asp) Applications:
- default.asp?catid=
- product.asp?id=
- news.asp?newsid=
- login.asp?username=&password=
- search.asp?q=
- blog.asp?postid=
- forum.asp?threadid=
- profile.asp?userid=
- admin.asp?username=&password=
- register.asp?username=&password=
3. ASP.NET (.aspx) Applications:
- default.aspx?catid=
- product.aspx?id=
- news.aspx?newsid=
- login.aspx?username=&password=
- search.aspx?q=
- blog.aspx?postid=
- forum.aspx?threadid=
- profile.aspx?userid=
- admin.aspx?username=&password=
- register.aspx?username=&password=
4. ColdFusion (.cfm) Applications:
- index.cfm?catid=
- product.cfm?id=
- news.cfm?newsid=
- login.cfm?username=&password=
- search.cfm?q=
- blog.cfm?postid=
- forum.cfm?threadid=
- profile.cfm?userid=
- admin.cfm?username=&password=
- register.cfm?username=&password=
5. Java Server Pages (.jsp) Applications:
- index.jsp?catid=
- product.jsp?id=
- news.jsp?newsid=
- login.jsp?username=&password=
- search.jsp?q=
- blog.jsp?postid=
- forum.jsp?threadid=
- profile.jsp?userid=
- admin.jsp?username=&password=
- register.jsp?username=&password=
When testing these endpoints, it's important to replace "
Remember, ethical hacking and responsible disclosure are key principles in bug bounty hunting. Always operate within the scope of the bug bounty program and follow their guidelines.
As a bug bounty hunter, focusing on these common vulnerable endpoints can be a good starting point. However, it's crucial to understand that not all instances of these endpoints will be vulnerable, and there may be other, less common endpoints that are susceptible to SQLi attacks.
Stay curious, keep learning, and happy hunting!
