Description Florian Best

2020-07-09 11:08:07 CEST

The LDAP ACL's suggested in https://wiki.univention.de/index.php/Cool_Solution_-_User_Self-Service_with_extended_Attributes are vulnerable.

With these ACL'S a UCS@school student can make himself a UCS@school Admin.
(Why? See explanation in Bug #39952 comment 12).

Nowerdays, the manual ACL registration is also not necessary as you can simply set UCR variables:
ucr set self-service/ldap_attributes=univentionFreeAttribute1

The article was for old UCS versions only, I removed it leaving only the link for UCS 4.4 Self Service.
