Dear Zope 2.12/.13 (4.0) devels,
as far as i can see i may have found a serious security hole within Zope 2.12 / 2.13 (4.0 not tested yet) - I'm still investigate here further...
problem: ====== Even on fresh Installs of Zope and fresh created instances on it anonymous / remote users able to access acl_users/manage_users by the web WITHOUT AUTHENTICATION. They can edit / delete / create users and serving roles as they want. Other management screens (as manage_main or manage_access aso. are protected as usual).
In manage_access Manage user is only allowed for Manager (as by default).
I don't believe that is any new behaviour of newer Zope versions...
I've tested this with (last public) 2.13.10 and last 2.12.20 with python2.6.
If any of the devels want to have a test url pls contact me directly.
Fresh installed zope instances was configured with defaults configs, except setting "user zope" (and/or port-base). Tried it with now owner or the admin user as owner of the acl_users too.
Can anyone prove this here too? If so, any solution / security fix?
many thanks, best regards.
Niels.
