Published Apr 16, 2024CWE-863EPSS 0.19%

Overview

CVE-2024-27086 is a low-severity vulnerability. It was published on April 16, 2024 and has a CVSS 3.1 base score of 3.9 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.9, rated LOW. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

The MSAL library enabled acquisition of security tokens to call protected APIs. MSAL.NET applications targeting Xamarin Android and .NET Android (e.g., MAUI) using the library from versions 4.48.0 to 4.60.0 are impacted by a low severity vulnerability.

A malicious application running on a customer Android device can cause local denial of service against applications that were built using MSAL.NET for authentication on the same device (i.e., prevent the user of the legitimate application from logging in) due to incorrect activity export configuration. MSAL.NET version 4.60.1 includes the fix. As a workaround, a developer may explicitly mark the MSAL.NET activity non-exported.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
