Russ McRee, a security consultant for HolisticInfoSec.org, documented cross-site scripting (XSS) errors in five sites that prominently carry a logo declaring them to be Hacker Safe. As McRee documented in a blog post and accompanying video, the bugs make it possible for attackers to steal authentication credentials and redirect visitors to malicious websites.
All five of the sites subscribe to McAfee's HackerSafe certification service, which audits the security of websites on a daily basis to give visitors confidence they'll be safe when doing business there. Yet McRee was able to find the bugs by using advanced Google searches to pinpoint vulnerable web applications, and in at least one case, the XSS vulnerability has been on the customer's site since January.
"There's a responsibility to the consumer that really seems to be missing in that service," McRee told us. "The average consumer assumes that because I see that label I must be safe."
The five vulnerable sites include Alsto.com, Delaware Express, BlueFly, Improvements Catalog and Delightful Deliveries. We asked all five for comment but only one of them, Delightful Deliveries, responded. "As the #1 leading seller of Gift Baskets, security is a top priority to us and our customers, we will work with HackerSafe and our development team to resolve this issue," a representative said. He is unaware of any breaches affecting the site, he added.
A McAfee spokeswoman said the company rates XSS vulnerabilities less severe than SQL injections and other types of security bugs. "Currently, the presence of an XSS vulnerability does not cause a web site to fail HackerSafe certification," she said. "When McAfee identifies XSS, it notifies its customers and educates them about XSS vulnerabilities."
These are only the latest Hacker Safe sites to be outed. In January, researchers from XSSed.com, documented 62 websites subscribing to the service that were vulnerable to XSS vulnerabilities. A Hacker Safe spokesman told InformationWeek at the time the bugs couldn't be used to hack a server.
The vulnerabilities also raise the question of so-called payment card industry (PCI) requirements for businesses that process credit card payments. Websites that contain XSS vulnerabilities almost certainly don't comply, McRee says, and yet most of the sites continue to accept credit cards. But we'll leave deficiencies in that set of requirements for another day.
McAfee has had three months to fix the deficiencies of this program, but so far we see no evidence it's done so. We're all for services that help websites stay on top of rapidly moving security threats. But there's a term for programs that declare their customers Hacker Safe while failing to catch easily spotted XSS flaws. It's called a rubber stamping, and it's time it stopped. ®
