> A Nessus scan pinged my test cluster because the Accumulo monitor allows HTTP TRACE requests. (ref: [an overview of the general problem class|http://www.cgisecurity.com/whitehat-mirror/WH-WhitePaper_XST_ebook.pdf])
> The issue isn't bad unless
> * there's a same-origin-policy bypass for the user browser
> * there's an auth token we care about
> Exploits the bypass the same-origin-policy happen, so it's best to clean up server side if possible.
> The only auth tokens present in the Monitor are when we make use of the ShellServlet from ACCUMULO-196. We rely on the session state for auth, so there isn't a risk of leaking auth info directly, but we would leak the session id. 
> The CSRF added in ACCUMULO-2785 means just the session id wouldn't be enough for impersonation, but if an attacker can read one requested page we have to presume they can read another.
> We should clean up our configs to disallow HTTP TRACE as a proactive measure.
> Marking minor since an attack vector would need an enabling vulnerability on the client side.
