KB4015068: Security Update for the LDAP Elevation of Privilege Vulnerability (April 2017)

high Nessus Plugin ID 99306
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Windows host is affected by an elevation of privilege vulnerability.


The remote Windows host is missing security update KB4015068. It is, therefore, affected by a flaw in LDAP due to buffer request lengths not being properly calculated. An unauthenticated, remote attacker can exploit this, via specially crafted traffic sent to a Domain Controller, to run processes with elevated privileges.


Apply security update KB4015068.
