vendor statues: they have been informed
Vulnerable versions: ikonboard 3.0.1
ikonboard 3.0.2
ikonboard 3.0.3(the version they
use on their site)
Severity: Malicious users can steal session cookies,
allowing administrative access to the admin panel
Problem:
Ok the problem is in the way the [img] tags check for
the "http://";. The [img] tags checks for the "http://";
when you posting a new topic but it doesnt check for
it while your editing one. So it will allow you to insert
malacious code while you editing a post.
Proof of concept:
Make a new post, then "EDIT" the post and in the
body of the post insert this code
[IMG]javascript:alert(document.cookie)[/IMG]
an alert box should pop up displaying your cookies!
Fix:
make [IMG] tags check for "http://"; when editing a
post.
