Microsoft: >> Windows Server 2016 >> 10.0.14393.7159 Security Vulnerabilities
Summary:
As of July 8, 2025 Microsoft has completed mitigations to address this vulnerability. See KB5042562: Guidance for blocking rollback of virtualization-based security related updates and the Recommended Actions section of this CVE for guidance on how to protect your systems from this vulnerability.
An elevation of privilege vulnerability exists in Windows based systems supporting Virtualization Based Security (VBS), including a subset of Azure Virtual Machine SKUS. This vulnerability enables an attacker with administrator privileges to replace current versions of Windows system files with outdated versions. By exploiting this vulnerability, an attacker could reintroduce previously mitigated vulnerabilities, circumvent some features of VBS, and exfiltrate data protected by VBS.
Update: July 10, 2025
Microsoft has addressed this vulnerability for Windows 10 1507, Windows 10, version 1607, Windows 10, version 1809, and Windows Server 2016 and Windows Server 2018. This ensures that mitigations are available to protect all supported versions of Windows 10 and Windows 11 from this vulnerability. See the available mitigations and deployment guidelines described in KB5042562: Guidance for blocking rollback of virtualization-based security related updates.
Update: August 13, 2024
Microsoft has released the August 2024 security updates that include an opt-in revocation policy mitigation to address this vulnerability. Customers running affected versions of Windows are encouraged to review KB5042562: Guidance for blocking rollback of virtualization-based security related updates to assess if this opt-in policy meets the needs of their environment before implementing this mitigation. There are risks associated with this mitigation that should be understood prior to applying it to your systems. Detailed information about these risks is also available in KB5042562.
Details:
A security researcher informed Microsoft of an elevation of privilege vulnerability in Windows 10, Windows 11, Windows Server 2016, and higher based systems including Azure Virtual Machines (VM) that support VBS. For more information on Windows versions and VM SKUs supporting VBS, reference: Virtualization-based Security (VBS) | Microsoft Learn.

A remote code execution vulnerability exists in the way that the MSHTML engine improperly validates input.
An attacker could execute arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
In a HTML editing attack scenario, an attacker could trick a user into editing a specially crafted file that is designed to exploit the vulnerability.
The security update addresses the vulnerability by modifying how MSHTML engine validates input.

A remote code execution vulnerability exists when Microsoft Edge PDF Reader improperly handles objects in memory. The vulnerability could corrupt memory in such a way that enables an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit the vulnerability, in a web-based attack scenario, an attacker could host a website that contains malicious PDF content. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted PDF content that could exploit the vulnerability. However, in all cases an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to take action. For example, an attacker could trick a user into clicking a link that takes the user to the attacker's site.
The security update addresses the vulnerability by modifying how Microsoft Edge PDF Reader handles objects in memory.

A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.
The security update addresses the vulnerability by modifying how the scripting engine handles objects in memory.
