Executive Summary Exposure of sensitive information to an unauthorized actor in Microsoft Authenticator allows an unauthorized attacker to disclose information over a network. Exploitability The following table provides an exploitability assessment for this vulnerability at the time of original publication. Publicly disclosed No Exploited No Exploitability assessment Exploitation Less Likely FAQ **What type of information could be disclosed by this vulnerability? ** This vulnerability could expose a sign-in access token for a user’s work account. If disclosed, that token could allow access to data and services that the user is authorized to use, potentially including sensitive organizational information. How could an attacker exploit this vulnerability? An attacker could attempt to trick a user into interacting with a malicious request that appears legitimate. When the user approves the request, the attacker could cause the app to obtain an access token on the user’s behalf and send it to a location controlled by the attacker, without the user being clearly informed about what access is being granted. Do users need to take any action to receive the fix for the Authenticator app issue on Android? Users who have automatic app updates enabled on their Android device will receive the fix without any action required. Users who do not have auto-update enabled must manually update the Microsoft Authenticator app to the latest version via the Google Play Store to ensure they receive the fix. According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability? An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
