Hướng nghiên cứu

This is a Microsoft security bulletin posted in the PowerShell Announcements repository, not a request for a code change, so there is no file, test or entry point to work from. The text names the affected PSResourceGet and PowerShell versions and the fixed releases, and the issue was published 911 days ago with no comments or linked pull requests. Nothing here defines a task a newcomer can complete, so it is not suitable as a first contribution.

Microsoft Security Advisory CVE-2024-0057 | NuGet Client Security Feature bypass Vulnerability

Executive Summary

Microsoft is releasing this security advisory to provide information about a vulnerability in 7.4 and Microsoft.PowerShell.PSResourceGet 1.0.3. This advisory also provides guidance on what developers can do to update their applications to address this vulnerability.

A security feature bypass vulnerability exists when Microsoft .NET Framework-based applications use X.509 chain building APIs but do not completely validate the X.509 certificate due to a logic flaw. An attacker could present an arbitrary untrusted certificate with malformed signatures, triggering a bug in the framework. The framework will correctly report that X.509 chain building failed, but it will return an incorrect reason code for the failure. Applications which utilize this reason code to make their own chain building trust decisions may inadvertently treat this scenario as a successful chain build. This could allow an adversary to subvert the app's typical authentication logic.
