Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has krb5 packages installed that are affected by multiple vulnerabilities:

- MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a linkdn and containerdn database argument, or by supplying a DN string which is a left extension of a container DN string but is not hierarchically within the container DN. (CVE-2018-5730)

- MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to cause a denial of service (NULL pointer dereference) or bypass a DN container check by supplying tagged data that is internal to the database module.
(CVE-2018-5729)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL krb5 packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
