One of the cardinal rules of computer programming is to never trust your input. This holds especially true when your input comes from users, and even more so when it comes from the anonymous, general public. Apparently, the developers at Oklahoma’s Department of Corrections slept through that day in computer science class, and even managed to skip all of Common Sense 101. You see, not only did they trust anonymous user input on their public-facing website, but they blindly executed it and displayed whatever came back.
The result of this negligently bad coding has some rather serious consequences: the names, addresses, and social security numbers of tens of thousands of Oklahoma residents were made available to the general public for a period of at least three years. Up until yesterday, April 13 2008, anyone with a web browser and the knowledge from Chapter One of SQL For Dummies could have easily accessed – and possibly, changed – any data within the DOC’s databases. It took [me] all of a minute to figure out how to download 10,597 records – SSNs and all – from their website.
The article is pretty funny (i.e., "and even managed to skip all of Common Sense 101.") but it looks like ~ 10K records were compromised. Small number in comparison to some of the compromises these days, but it's still 10,000 people's personal info.
This guy has screenshots of the whole process, including the SQL injections used! Considering it's a state DOC website, I'm not sure I'd be "poking around" for fear of ending up there myself.
