Microsoft Azure Active Directory B2C Elevation of Privilege Vulnerability

Authorization bypass through user-controlled key in Microsoft Azure Active Directory B2C allows an unauthorized attacker to elevate privileges over a network.

Azure Active Directory Information Disclosure Vulnerability

An information disclosure vulnerability manifests when a user or an application uploads unprotected private key data as part of an authentication certificate keyCredential  on an Azure AD Application or Service Principal (which is not recommended). This vulnerability allows a user or service in the tenant with application read access to read the private key data that was added to the application. Azure AD addressed this vulnerability by preventing disclosure of any private key values added to the application. Microsoft has identified services that could manifest this vulnerability, and steps that customers should take to be protected. Refer to the FAQ section for more information. For more details on this issue, please refer to the MSRC Blog Entry.

Azure Active Directory Elevation of Privilege Vulnerability

Improper authentication in Azure Active Directory allows an unauthorized attacker to elevate privileges over a network.

Azure 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."

The Microsoft Azure Active Directory Passport (aka Passport-Azure-AD) library 1.x before 1.4.6 and 2.x before 2.0.1 for Node.js does not recognize the validateIssuer setting, which allows remote attackers to bypass authentication via a crafted token.

An elevation of privilege vulnerability exists in Microsoft Azure Active Directory Connect build 1.3.20.0, which allows an attacker to execute two PowerShell cmdlets in context of a privileged account, and perform privileged actions.To exploit this, an attacker would need to authenticate to the Azure AD Connect server, aka 'Microsoft Azure AD Connect Elevation of Privilege Vulnerability'.
