[Standard Disclaimer: I could always be wrong.....but.....]
In the most current update to Microsoft's Security Advisory about the WMF exploit (http://www.microsoft.com/technet/sec...y/912840.mspx), I believe that there are several mis-statements that should addressed in the "Mitigating Factors" section. 1) "In a Web-based attack scenario, an attacker would have to host a Web site that contains a Web page that is used to exploit this vulnerability." This is false. Attackers can post infected files to unsecured websites or photo blogs like Flickr. Hosting the website would add an unwanted trail to the hacker and is avoided by all but the most inexperienced hackers. While script kiddies will host this exploit, the more advanced exploitations are likely to pop up on websites NOT hosted by the attackers. In fact, all you have to do is ciew an infected image onscreen to launch the attack against your PC. 2) "Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail or Instant Messenger request that takes users to the attacker's Web site." Also not true. Pop-ups can also hold exploits used to take over a user's PC. As you are aware, you don;t have to do anything to get a pop-up to launch except visit a site that may have no knowledge of what is in the pop-up (other than any advertising agreements they have with the pop-up target site or ad reseller). Also not taken into account is the rather nasty habit that most websites (even sites like www.CNN.com) of hosting third-party images that are frequently retrieved from even a 4th, 5th or Xth party site. This increases the likelihood of an attack being launched via 3rd party images on even well-respected sites like www.cnn.com or www.cnet.com . 3) "In an e-mail based attack involving the current exploit, customers would have to click on a link in a malicious e-mail or open an attachment that exploits the vulnerability." This is not true for any user that reads thier email in HTML format. HTML emails automatically download and display images in HTML emails. This means that simply reading an HTML email can infect an unpatched machine. You don't have to click a thing. A little lower in the updated advisory Microsoft states "In Windows Server 2003, Microsoft Outlook Express uses plain text for reading and sending messages by default. When replying to an e-mail message that is sent in another format, the response is formatted in plain text.", indicating that they are aware of the HTML email vulnerability, but not making it clear that reading emails in HTML format can launch an attack without clicking on anything. 4) "At this point, no attachment has been identified in which a user can be attacked simply by reading mail." This is true and should be differentiated from #3's mis-statement. An attachment must be clicked to be viewed. Note the word "attachment". HTML emails (if read in HTML format) load thier images from servers ad display them automatically within the email when you view the HTML email. When reading an HTML email that contains and infected image file, you do not need to click anything for the exploit to be executed. The display of the image on your screen is all it takes to launch it's payload. Financial Times states "Unlike most attacks, which require victims to download or execute a suspect file, the new vulnerability makes it possible for users to infect their computers with spyware or a virus simply by viewing a web page, e-mail or instant message that contains a contaminated image." - at http://news.ft.com/cms/s/0d644d5e-7b...0779e2340.html 5) "This issue is not known to be wormable." Not true. An MSN Messenger worm has already been reported to be spreading in the wild - see http://www.f-secure.com/weblog/archi...ve-122005.html and http://www.viruslist.com/en/weblog?d...92530&return=1. If I've got anything wrong here (I'm not perfect either )....speak up.Jim |
