Talk // SQL Injection Isn't Dead: Smuggling Queries at the Protocol Level

Abstract // SQL injections seem to be a solved problem; databases even have built-in support for prepared statements, leaving no room for injections. In this session, we will go a level deeper: instead of attacking the query syntax, we will explore smuggling attacks against database wire protocols, through which remote, unauthenticated attackers can inject entire (No)SQL statements into an application's database connection. Using vulnerable database driver libraries as case studies, we will bring the concept of HTTP request smuggling to binary protocols. By corrupting the boundaries between protocol messages, we desynchronize an application and its database, allowing the insertion of malicious messages that lead to authentication bypasses, data leakage, and remote code execution.
