Since Sid3^effects published a single one of these 21 June 2010 -
http://www.exploit-db.com/exploits/13955/ - I figured the cat's out of
the bag...

His exploit works even on 1.8RC1, however it gets sanitized once it hits
the server (there's an ajax update that shows the marquee, but further
views render it inoperable).

The following were reported to Azrul back in March and patched in an
update 31 March 2010.


Persistent XSS
--------------
The following fields allow for persistent XSS in admin panel (requires
admin to edit profile & click the field):

status, mobile phone, land phone, state, city, website, college

test" onclick="alert(1)


Edit Details > Name field persistent XSS:
-----------------------------------------
t"/onmouseover="alert(1)

executes on avatars located on:
* admin edit user page
* the main jomsocial page in the members avatar field at the top
* affected user's profile
* who's online
* the wall posts
* group discussion replies (but not the initial discussion message)
* people search results
* compose message
* write message friend list multiselect
* new message notification
* inbox (main listing)
* inbox (while reading message)
* friends approval list
* online users mod
* latest members mod

possibly others...



Groups name field persistent XSS:
---------------------------------
g"/onmouseover="alert(1)//

mouseover executes on:

* latest groups
* group listing
* group search results
* frontend edit group form
* admin edit group modal

possibly others...



Messages Persistent XSS
-----------------------
subject & message fields do not filter html tags properly:

xss<img/src/onerror=alert(/xss/.source)//

occurs in both main inbox (subject) and while reading message (both)



Groups Album Description Persistent XSS
---------------------------------------
d"/onmouseover="alert(1)//

this XSS is rendered in the tips section of the album listing



Report **** Admin Persistent XSS
--------------------------------
"message" field is not properly sanitized, admin must view reports for
execution (no other interaction needed)

<img/src/onerror=alert(1)//

if POST data is tampered before submission, the report url can also be
exploited
doing so only requires minimal admin interaction in backend:

%23%22%2fonmouseover%3D%22alert%281%29%2f%2f

NOTE: it is possible to merely change the url hash, but then the form
will not send



Search People input Reflective XSS
----------------------------------
search people input: t"/onmouseover="alert(1)
