OWASP Top 10 .NET Protection: A Guide (Part 1)

The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications. In this article, I want to cover the first part of the TOP 10 vulnerabilities and how to protect against them using .NET.

1. Injection

What it is?

Almost any source of data can be an injection - vector, environment variables, parameters, external and internal web services, and all types of users. Injection flaws occur when an attacker can send hostile data to an interpreter. Injection vulnerabilities are often found in SQL, LDAP, XPath, or NoSQL queries, OS commands, XML parsers, SMTP headers, expression languages, and ORM queries. Injection can result in data loss, corruption, or disclosure to unauthorized parties, loss of accountability, or denial of access.

What to do?

SQL Injection

  1. Using an object-relational mapper (ORM) or stored procedures is the most effective way of countering the SQL Injection vulnerability.
  2. Use parameterized queries where a direct SQL query must be used.
  3. Practise Least Privilege - Connect to the database using an account with a minimum set of permissions required to do it's job i.e. not the same account

Good example:

var sql = @"Update [User] SET FirstName = @FirstName WHERE Id = @Id";
context.Database.ExecuteSqlCommand(
    sql,
    new SqlParameter("@FirstName", firstname),
    new SqlParameter("@Id", id));
