I am Kwan Kim who works for the Rogosin Institute (medical research company specialized
for Kidney disease in New York)
Recently we tried to use xwiki as an our wiki server.
So we configured the xwiki server on Redhat, MySQL & Glassfish environment and ask
vulnerability test team to test.
However they found several security issues.
And I am not a expert for the xwiki so I am not sure whether xwiki already has a solution
to fix the issues or not.
That’s why I would like to ask you about the security features of xwiki.
This is the security problems which the vulnerability team addressed below:
1. Cross Site Scripting (XSS): Script insertion at Name Field in the registration form.
When new user register, there is first and last name field. thesis fields allow javascript
code.
Is there any way we can put the some validation to prevent the javascript code ?
2. No controls for Account Creation
The vulnerability test team think it is too easy to create new account
Is there any way that new account need to get approval from admin user ?
3.Site discloses session tokens in multiple locations
It seems xwiki use session token through URL(GET). The vulnerability test team suggest to
use POST method instead GET.
Is there any option to use POST method instead of GET method to transmit the session token
information?
4.Username retrieval with no verification
When the user forget the username, the user can retrieve username with email address.
However it is not sent to email but show in the site.
The vulnerability test team think the hacker can get the username if they try many
different combination of email.
Is it possible xwiki only send the username by email instead of showing in the page ?
5. Password Validation is weak
It seems xwiki allow weak password to register new user.
Is it possible to use strong password only when new user registered in xwiki?
These are the all issue they addressed.
Please let me know the answer.
Thank you and have a good day

It's not very clear to me what this mean. In which context exactly the
javascript inserted in the user name is executed ?
Is there any way we can put the some validation to prevent the javascript code ?
2. No controls for Account Creation
The vulnerability test team think it is too easy to create new account
Is there any way that new account need to get approval from admin user ?
Its possible to disable registration and let admins create accounts
but I don't think there is any support for admin validation of self
registered users (but it's possible I missed it).
3.Site discloses session tokens in multiple locations
It seems xwiki use session token through URL(GET). The vulnerability test team suggest to
use POST method instead GET.
Is there any option to use POST method instead of GET method to transmit the session
token information?
It's not a really a all or nothing central place so we would need to
know where exactly you have this issue to see if there is a way to fix
it in a case by case basis.
4.Username retrieval with no verification
When the user forget the username, the user can retrieve username with email address.
However it is not sent to email but show in the site.

Would be great if you could create an issue about that on
http://jira.xwiki.org. Looks easy to fix, just need to discuss if we
should do it or not. On my side I did not know we were displaying the
user id in this page and I agree that it's probably not a good idea.
5. Password Validation is weak
It seems xwiki allow weak password to register new user.
Is it possible to use strong password only when new user registered in xwiki?
It's possible to add a lot of constraint in the registration form. See
http://extensions.xwiki.org/xwiki/bin/view/Extension/Administration%20Appli….
These are the all issue they addressed.
Please let me know the answer.
Thank you and have a good day

Thanks,

Is there any way we can put the some validation to prevent the
javascript code ?

Hi Thomas
Thanks for the reply.
I was out for a week.
I think I can apply the constraint you suggest during the registration.
Have a good day.
