Attempt an XSS exploit on commandlinefu.com

perl -pi -e 's/<a href="#" onmouseover="console.log('xss! '+document.cookie)" style="position:absolute;height:0;width:0;background:transparent;font-weight:normal;">xss</a>/<\/a>/g'
Mouse around the title of this item, and note that your cookies are being logged to the console. If I were evil, I could instead send everyone's cookies to my site, and then post up-votes on all my submissions using their cookies, and try to delete every other submission, until clfu was completely pwned by me, redirecting people to malware and porn sites, and so on. Update - now fixed.

What Others Think

Ok, very good. Issue now fixed - was due to a recent attempt to parse commands for <CTRL+A> like insertions. Managed to introduce a security hole at the same time. I would probably rather you emailed me instead of posting the recipe to the world though.

I found it educational, as a user of commandlinefu. But as I site owner i know how @root feels.

Hey, thanks! I found it by accident, and since I had to post a submission in order to test it, I figured this would get your attention. For all I know, someone was already using it quietly. I'll email you next time if I spot something like this.
