The company sifted through data from more than 650 organizations and tens of thousands of real-world websites continually monitored by WhiteHat Sentinel Services. The average number of serious* vulnerabilities identified per website was 56, continuing the downward trend from 79 in 2011 and 230 in 2010. As far as the Top Ten most prevalent vulnerability classes in 2012, the list is relatively close to last years, though Information Leakage surpassed Cross-Site Scripting yet again: 55 percent of websites.”]
