Project: OpenID Connect Microsoft Azure Active Directory client [1]
Date: 2021-November-17
Security risk: *Moderately critical* 14∕25
AC:Complex/A:None/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Access Bypass

Description: 
This module enables users to authenticate through their Microsoft Azure AD
account.

The module does not sufficiently check authorization before updating user
profile information in certain non-default configurations. This could lead a
user being able to hijack another existing account.

This vulnerability is mitigated by the fact that an attacker must have
knowledge of user accounts that have the administrator role or accounts with
the 'Set a password for local authentication' permission. In addition the
site must be configured with the 'Update email address in user profile'
setting turned on.

Solution: 
Install the latest version:

   * If you use the OpenID Connect Microsoft Azure Active Directory client
     module 7.x-1.x, upgrade to OpenID Connect Microsoft Azure Active 
Directory
     client 7.x-1.2 [3]
   * If you use the OpenID Connect Microsoft Azure Active Directory client
     module 8.x-1.x, upgrade to OpenID Connect Microsoft Azure Active 
Directory
     client 8.x-1.4 [4]
