CVE-2017-8613
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAzure AD Connect Password writeback, if misconfigured during enablement, allows an attacker to reset passwords and gain unauthorized access to arbitrary on-premises AD privileged user accounts aka "Azure AD Connect Elevation of Privilege Vulnerability."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis vulnerability is a misconfiguration in Azure AD Connect's password writeback feature. When enabled improperly, it allows an attacker to reset passwords for arbitrary on-premises Active Directory privileged user accounts, enabling unauthorized elevation of privilege to domain admin or equivalent level access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Azure AD Connect versionLocate the Azure AD Connect installation on the server and check the installed version. This can typically be found in Add/Remove Programs, the Azure AD Connect wizard, or by checking assembly version of the Azure AD Connect binaries.Affected if The installed version is 1.1.524.0 or earlier.
-
Verify password writeback is enabledOpen the Azure AD Connect configuration wizard or check the Azure AD Connect synchronization service settings. Look for the password writeback option in the optional features section.Affected if Password writeback is enabled in the Azure AD Connect configuration.
-
Check Azure AD SSPR settings for writeback permissionsReview the Azure Active Directory admin center or MS Online powershell module (Get-MsolCompanyInformation) to see which users or groups are permitted to perform self-service password reset with writeback to on-premises.Affected if The password writeback configuration does not restrict which users can have passwords written back, or allows writeback for users with privileged on-premises accounts.
-
Inspect on-premises AD account used for syncCheck the permissions of the Azure AD Connect service account (typically MSOL_*) in Active Directory. Verify whether this account has been granted elevated permissions beyond what is required for password writeback.Affected if The sync account has excessive permissions such as domain admin, enterprise admin, or reset password rights on privileged user objects.
A user is affected if Azure AD Connect version 1.1.524.0 or earlier is installed with password writeback enabled, and the writeback configuration or AD account permissions are not properly scoped to prevent password resets for privileged on-premises accounts.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReview and correct the Azure AD Connect password writeback configuration to ensure proper permission scoping and restrict which users can have passwords written back, following Microsoft's recommended secure configuration guidelines.
