Vulnerability check for zcs 6.0.6.1

[chandu]

Hi Guys,

I am planning to upgrade my setup from zcs 5.0.13 to zcs 6.0.6.1 tmorrow. I just ask my VA team to do testing and they sent me couple of issues.

As I read in release notes, Anonymous searches of the LDAP directory are no longer enabled.

But as per VA testing we found :

###############################################

Synopsis :

The remote LDAP server may disclose sensitive information.

Description :

The remote LDAP server supports search requests with a null, or empty,
base object. This allows information to be retrieved without any
prior knowledge of the directory structure. Coupled with a NULL BIND,
an anonymous user may be able to query your LDAP server using a tool
such as 'LdapMiner'.

Note that there are valid reasons to allow queries with a null base.
For example, it is required in version 3 of the LDAP protocol to
provide access to the root DSA-Specific Entry (DSE), with information
about the supported naming context, authentication types, and the
like. It also means that legitimate users can find information in the
directory without any a priori knowledge of its structure. As such,
this finding may be a false-positive.

Solution :

If the remote LDAP server supports a version of the LDAP protocol
before v3, consider whether to disable NULL BASE queries on your LDAP
server.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:P/I:N/A:N)
