Scripting is baaaad
So, on Monday I reported on why you shouldn’t allow Flash on your network with the article: Nmap 127.0.0.1: Flash Style . Kind of hinting toward how a malicious site could scan your internal network without triggering your firewall, IPS/IDS, or sometimes even a host based firewall/ips. Today, I have a new threat that is hot off of BugTraq. A researcher at SecNiche.org by the name of Aditya K Sood found a vulnerability in Microsoft Internet Explorer’s PopUp Blocker. An incredible small amount of code can be executed via JavaScript to add a site to the “Allowed” popup list. You can find the write up HERE (PDF).
Isn’t it about time that you start using Firefox with Adblock Plus and NoScript ? Might as well throw in another good add-on called StumbleUpon as well.
::UPDATE:: It has been confirmed that this only works when the html document is opened locally. The reason I didn’t wipe the article all together is the fact that things like this usually are a seed to find an actual working way to get this done.
