New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisAn application installed on the remote Windows host is affected by an elevation of privilege vulnerability.
DescriptionThe version of Azure Active Directory (AD) Connect installed on the remote Windows host is prior to 1.1.553.0, and the password writeback setting is enabled. It is, therefore, affected by an elevation of privilege vulnerability due to improper permissions being granted when enabling the password writeback setting. An authenticated, remote attacker can exploit this to reset users' passwords and gain access to arbitrary on-premises AD privileged user accounts.
Note that Nessus did not verify if the reset password permission was granted to on-premises AD user accounts.
SolutionUpgrade to Azure AD Connect version 1.1.553.0 or later. Alternatively, apply the mitigation steps listed in the vendor advisory.
