Report: 90% of Web Sites Vulnerable to Hackers

New study claims Cross-Site Scripting attacks are all over the place. Should we be afraid?

internetnews.com: We all know that some Web sites suffer from security vulnerabilities -- but 90 percent of them?

In a new report, security researcher Whitehat Security said it found a staggering nine out of 10 Web sites have some type of serious vulnerability that a hacker could potentially exploit.

The study, which examined more than 600 sites including those of Fortune 500 firms, found a number of different vulnerabilities common across the Internet, with Cross-Site Scripting (XSS) vulnerabilities dominating the rankings.

In fact, Whitehat claims that 70 percent of the Web sites it surveyed were at risk from some sort of XSS attack. That figure dwarfs the No. 2 culprit in the firm's survey, SQL injection, which comprised only 4 percent of the firm's total surveyed vulnerabilities.
