User Agent XSS anyone?

[Zack Payton <zpayton () gmail com>]

Hi all,

I was just curios if anyone was aware of any interesting ways to
exploit user-agent based xss.
I suppose it would be easy in conjunction with HTTP response
splitting, but is anyone aware of any other vectors beside those
present in custom browser extensions?
I am interested in hearing about all vectors though, even those in
custom browser extensions.

Thank you!

Sincerely,
Z
