Bugs & Viruses Columbia University researchers claim millions of HP printers could be open to remote attack via unsecured Remote Firmware Updates. Cybercriminals could steal personal information or attack otherwise secure networks. HP agrees there is a theoretical security problem but says no customer has ever reported unauthorized printer access. The company denies some of the claims and is still investigating others.

Actually, you can't do that with JavaScript. As I mentioned the attacker just places an -tag.

Well, I guess you can do that with JavaScript but it doesn't have any advantage over using an image.

They might use JavaScript to generate a long list of -tags to try different IP-addresses though.

Just sending a longer HTML-page is easy too ofcourse.

So the only thing you are protecting yourself against in this case is an attacker which expects JavaScript to be available and working.


You misunderstand. NoScript's name is unfortunate because it hasn't merely whitelisted Javascript for a very long time.

The ABE module hooks into Firefox's HTTP subsystem and is capable of inspecting and refusing any request not made completely independently by a plugin like Java or Flash.

By design, it does intercept exploits made using <img> tags, stylesheet <link>s and @imports, and all manner of other mechanisms attackers can imagine.

(Of course, it doesn't block exploits via Java or Flash-native HTTP, which is why I also use the securely-implemented FlashBlock-like functionality too)
