In this article “These days SQL injection vulnerabilities may seem like a dime a dozen, but creative penetration testers and attackers continue to come up with new ways to take advantage of this vulnerability class that developers persist in allowing to linger like a bad cold. Last month at BSides Las Vegas, a pair of researchers from FishNet Security demonstrated that type of creativity with a new SQL injection attack technique against websites that serve up binary file content like PDFs from dynamically built URLs.

Their methods give attackers the means to stealthily extract data and serve up hidden malware by attacking SQL injection vulnerabilities on these types of sites — even if the back-end database serving up content to the Web application is hardened in every other way.”
