Description Jan Lieskovsky 2010-04-01 12:22:08 UTC

Jamie Strandboge of the Ubuntu Security Team reported:
  [1] https://bugs.launchpad.net/ubuntu/+source/moin/+bug/538022

a cross-site scripting (XSS) flaw, present in the Moin's Despam
action module, providing possibility mass to revert changes done
by some specific author / bot. Unprivileged Moin user could provide
a specially-crafted HTML page and trick the privileged user into
running the Despam action on it, leading to disclosure of sensitive
information, denial of 'revert changes service' or potentially,
to execution of arbitrary JavaScript code with the privileges
of the privileged Moin user.

Comment 1 Jan Lieskovsky 2010-04-01 12:23:52 UTC

Public reproducer from Jamie (from [1]):

XSS in Despam page. To reproduce:
1. http://localhost/MyWiki/TestXSS<blink>WARNING</blink>
2. click 'Create new empty page' with text 'Describe TestXSS<blink>WARNING</blink> here.'
3. click Save
4. Login as someone who can Despam (eg, superuser)
5. go to http://localhost/MyWiki/TestXSS%3Cblink%3EWARNING%3C/blink%3E?action=Despam
6. click the appropriate 'Select Author' link (usually the 'localhost' link. If this doesn't work, then login as a non-superuser, make a small edit to the page (eg, remove 'here' from the first line), then log back in as superuser and try to Despam again, clicking 'Select Author' for the user that just made the edit)
7. click 'Revert All!'
8. observe a lot of blinking text (from the pagename)
