[Full-disclosure] Open Xchange XSS

[Thomas Pollet]

Open Xchange webmail (<=0.8.1-6) suffers from xss.

Vendor response:
For the commercial OX you don't need this as there exists additional
security
options where you will not able to use this session. It's a general problem
for
all web based mailers and some of them try to filter such scripts, some of
them
do not and show a warning instead that the document may contains "dangerous
content". But you will never be able to filter all possible scriptings.
Displaying HTML content is ALWAYS an unsecure option, so it is recommended
to
disable "Inline HTML" at the WebMail options. Anyway, I will check if I can
make
some basic filter to get most of such tags.

Cheers,
 Thomas
