#47308 unintended information exposure when anonymous access is set to rootdse
Closed: wontfix Opened by nkinder.

Closed: wontfix
Reopen Issue

When nsslapd-allow-anonymous-access is set to "rootdse", I would expect DS to
return only rootDSE entry to anonymous user. But it returns any LDAP entry as
with enabled anonymous access if the search is done with scope set to BASE. ACIs still apply, so anonymous users would only be able to see data that is explicitly granted anonymous access by an ACI.

Steps to Reproduce:
1. Set nsslapd-allow-anonymous-access in cn=config to "rootdse"
2. Try to get an entry with scope=BASE as anonymous user

Actual results:
Entry is returned

Expected results:
Access is rejected.

This issue has been assigned CVE-2013-1897.

Bug description: The actual search base was not being checked
at all. There was a check for the search base when this feature
was initially implemented, but it was inadvertently removed when
changes were made to reduce the DN normalization throughout the
source tree (commit f6397113666f06848412bb12f754f04258cfa5fa).

Fix description: This patch adds the search base check back.
