[Full-disclosure] RSS Injection in Sage part 2

[David Kierznowski]

RSS Injection is Sage part 2

2 months ago, both pdp and myself released a vulnerability and proof
of concept exploit for Sage. (see:
http://michaeldaw.org/md-hacks/cross-context-scripting-with-sage/).
This issue was resolved in Sage release 1.3.7 (
http://mozdev.org/bugs/show_bug.cgi?id=15101). I  found a new
vulnerability which affects the latest version, Sage 1.3.8. In
addition to the XSS vulnerability, it should be noted (as with the
previous vulnerability) this issue occurs within the Local Browser
Context. This means arbitrary file access etc.
