Technical details
The adjoin utility in BoKS Server Agent uses a weak password generation algorithm when creating or renewing machine-account passwords during Active Directory join operations. An attacker who can estimate the generation timestamp can feasibly predict the resulting password through brute-force enumeration, circumventing the intended security of machine-account credentials.
