liang xie commented on HBASE-3546:
----------------------------------

I tried to repro on 0.94 but failed, seems jamon(RegionListTmpl.jamon) did the 
HTML escape.  I saw the "<script>alert('js')</script>" text in Start/End Key 
columns from WebUI, w/o JS code running.

On 0.90, there's no escape in regionserver.jsp, this issue only exists on 
0.90(or before), seems didn't worth to fix it?

Please correct me if i am wrong:)

> There are possibilities of XSS in the WebUI.
> If ColumnFamily or Region splitting keys are like
> Bytes.toBytes("<script>alert('js')</script>")
> then browsers run the JavaScript code.
> I tested on HBase-0.90.0 .
