Plesk PCI 2 Compliance - Session Fixation

M

md3vxx

Guest
Does anyone know how to correctly disable session fixation within Plesk?

I have defined:

session.use_cookies = 1
session.use_only_cookies = 1

Within /usr/local/psa/admin/conf/php.ini and restarted the Plesk server service:

/etc/init.d/sw-cp-server restart

But Plesk continues to be vulnerable:

As you can see the server fixes the cookie (Set-Cookie) ssent by the client. You can run this server using the Firefox Live Headers plugin.

I am writing a PCI 2.0 compliance document for Plesk based on the original, http://www.md3v.com/pci-compliance-for-parallels-plesk, but am unable to resolve this issue.
