SELECT code_execution FROM * USING SQLite: Eggheads lift the lid on DB security hi-jinks
At the DEF CON hacking conference in Las Vegas on Saturday, infosec gurus from Check Point are scheduled to describe a technique for exploiting SQLite, a database used in applications across every major desktop and mobile operating system, to gain arbitrary code execution.
In a technical summary provided to The Register ahead of their presentation, Check Point's Omer Gull sets out how he and his colleague Omri Herscovici developed techniques referred to as Query Hijacking and Query Oriented Programming, in order to execute malicious code on a system. Query Oriented Programming is similar in a way to return oriented programming in that it relies on assembling malicious code from blocks of CPU instructions in a program's RAM. The difference is that QOP is done with SQL queries.
[...] It must be stressed, though, that to pull off Check Point's techniques to hack a given application via SQLite, you need file-system access permissions to alter that app's SQLite database file, and that isn't always possible. If you can change a program's database file, you can probably get, or already have achieved, code execution on the system by some other means anyway.
Nonetheless, it's a fascinating look into modern methods of code exploitation, and a neat set of discoveries.

But there can't be any production applications that use sqllite for anything important. No developer is that stupid. Not even the ones who replaced the start menu with whatever it is Windows 10 has.

The browser and OS you posted that with probably uses SQLite. SQLite is probably the single, most widely deployed piece of software on the planet.

It's also a great example of an airtight hatchway problem [microsoft.com], someone who can essentially add an interception proxy to SQLite can hack SQLite. It's a neat party trick, but not an actual security problem.
