New vulnerability strikes heart of Web 2.0
More worries for the beta software fraternity
Whatever you think of "Web 2.0" (it's really not mandatory to release everything in permanent beta) you probably thought that this generic approach to mashups, Ajax and all that good stuff didn't change the usual coding "good practice" rules much.

Obviously, this vulnerability needs to be accepted by the Web 2.0 community as a whole but Jeremiah Grossman, CTO of WhiteHat Security has already verified its reality in some circumstances.
"New technology often leads to new risks and opens unforeseen avenues of malicious attack," he says. "Once understood, developers need to ensure the necessary safeguards are in place when they break new ground. Those responsible for the security of Web 2.0 deployments need to take this issue seriously and implement the steps necessary to resolve the issue before the risk results in an incident."
The solution to this issue really lies in the frameworks and any sample code they ship. It's not enough to make sure that your framework can be made secure; any code examples you provide must exemplify this "good practice" where appropriate. Luckily, Chess finds that most frameworks providers are receptive to this view and will address the problem in their next release (as will Fortify, in the next release of its security analysis tools); although a few people still adhere to the rather old-fashioned "not our problem if people are stupid" view.
