vb.org Archive - View Single Post - Template Headinclude XSS Bug Internet Explorer

thincom2000 · #13 04-04-2009, 06:10 AM

I'm confused. Is the XSS caused by <title> being the first element in the <head> tag, or is it caused because <script> tags are placed after it in the <head> tag. Is this simply a browser quirk or is it because your $headinclude or intended <script> might be untrustworthy?

As you can see the problem of not fully explaining the attack points, while preventing people from having the knowledge to execute attacks, also prevents coders from being able to prevent them because they don't have all the information, and get ideas such as "I guess I can't place ANY code after the <title> tags but before the </head> tag in ANY web page (not just vB pages)."
