Yes sir, words to live by. Like the doctor that tells the patient “Don’t do that”, when the patient tells of something that causes a problem, Microsoft is full of salient advice.
That seems to be the best they can do for now, as the problem highlighted by an outside source seems to be fully proven – pressing the key for help could get you into big trouble if you are using Internet Exploder and a version of Windows before Vista.
Does anyone else find it odd that all of these things are appearing which might otherwise point to a concerted effort by Microsoft to force an operating system upgrade? Why not simply say to the greater public that the problem is internet Exploder, not earlier versions of Windows.
ComputerWorld has their own take on it –
Microsoft told Windows XP users today not to press the F1 key when prompted by a Web site, as part of its reaction to an unpatched vulnerability that hackers could exploit to hijack PCs running Internet Explorer (IE).
In a security advisory issued late Monday, Microsoft confirmed the unpatched bug in VBScript that Polish researcher Maurycy Prodeus had revealed Friday, offered more information on the flaw and provided some advice on how to protect PCs until a patch shipped.
“The vulnerability exists in the way that VBScript interacts with Windows Help files when using Internet Explorer,” read the advisory. “If a malicious Web site displayed a specially crafted dialog box and a user pressed the F1 key, arbitrary code could be executed in the security context of the currently logged-on user.”
Last week, Prodeus called the bug a “logic flaw,” and said attackers could exploit it by feeding users malicious code disguised as a Windows help file — such files have a “.hlp” extension — then convincing them to press the F1 key when a pop-up appeared. He rated the vulnerability as “medium” because of the required user interaction.
Windows 2000, Windows XP and Windows Server 2003 are impacted by the bug, said Microsoft, and any supported versions of Internet Explorer (IE) on those operating systems — including IE6 on Windows XP — could be leveraged by attackers. Previously, Prodeus had said that users running IE7 and IE8 were at risk, but had not called out IE6.
Until a patch is ready, users can protect themselves by not pressing the F1 key if a Web site tells them to, said Microsoft.
“As an interim workaround, users are advised to avoid pressing F1 on dialogs presented from Web pages or other Internet content,” said David Ross with the Microsoft Security Response Center (MSRC) engineering staff in a blog entry on Monday.
Again, for those that are hard of learning, such as Microsoft help personnel types, the best fix is to stop using Internet Exploder entirely, and by the time the fix comes out, the user base will be effectively weaned off the useless piece of garbage that has proven to be more problematic than George Bush during the years from 2001 to 2009.
“The prompt can appear repeatedly when dismissed, nagging the user to press the F1 key,” Ross added.
The security advisory made the same recommendation: “Our analysis shows that if users do not press the F1 key on their keyboard, the vulnerability cannot be exploited.”
Users can also stymie attacks by disabling Windows Help. The advisory explained how to entering a one-line command at a Windows command-line prompt to lock down the Help system.
The company took Prodeus to task for taking the bug public, something it regularly does when researchers disclose a vulnerability or post sample attack code before a patch is available.
“Microsoft is concerned that this vulnerability was not responsibly disclosed, potentially putting customers at risk,” said Jerry Bryant, a senior manager with the MSRC, in an e-mail. By Prodeus’ account, he notified Microsoft of the flaw Feb. 1, about four weeks before publishing his findings.
Microsoft has not set a timeline for a fix, saying only that, “Microsoft will take the appropriate action to help protect our customers.” The next scheduled security patch date for the company is March 9.
Although it does not rate the severity of vulnerabilities in its advisories, Microsoft noted that hackers exploiting the VBScript flaw using Windows Help and Internet Explorer could grab complete control of a Windows system.
Customers running Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2 are safe from such attacks, Microsoft said.
Finally, a positive thing about running Windows Vista. You knew there had to be at least one.
