Endpoint Vulnerability

Microsoft: Active Directory Elevation of Privilege Vulnerability

Description

An elevation of privilege vulnerability exists in Active Directory Forest trusts due to a default setting that lets an attacker in the trusting forest request delegation of a TGT for an identity from the trusted forest. To exploit this vulnerability, an attacker would first need to compromise an Active Directory forest. An attacker who successfully exploited this vulnerability could request delegation of a TGT for an identity from the trusted forest. This update addresses the vulnerability by ensuring new Active Directory Forest trusts disable TGT delegation by default. The update does not change existing TGT delegation configurations.
