In a recent post to his blog Rafael Dohms reminds readers to not forget about the security of their applications because it can be "a huge mistake which can take a turn for the worse."

I have ran into lots of excuses for ignoring security in the past, one of them is the recurring "This is just a simple application, it has no sensitive data", this may be a valid point for the person repeating it like a mantra, especially because this person is generally suffering of great pressures , short timeframes and a lack of proper management ready to deal with web development. [...] Whatever the reason is for neglecting security the consequences can escalate much higher then the "non-sensitive data" of the application.

He looks at a specific case where a security issue was found in a large Brazillian mobile company's website that was caused by improper filtering on a $_GET parameter, leaving it open to possible attack. Through it, he could load the information for sensitive system-related files and found more on the machine than just the site he was working with.
