Summary
Microsoft was notified that an elevation of privilege vulnerability exists in Windows Update, potentially enabling an attacker with basic user privileges to reintroduce previously mitigated vulnerabilities or circumvent some features of Virtualization Based Security (VBS). However, an attacker attempting to exploit this vulnerability requires additional interaction by a privileged user to be successful.
Microsoft has developed a security update to mitigate this threat which was made available October 08, 2024 and is provided in the Security Updates table of this CVE for customers to download. Note: Depending on your version of Windows, additional steps may be required to update Windows Recovery Environment (WinRE) to be protected from this vulnerability. Please refer to the FAQ section for more information. Guidance for customers who cannot immediately implement the update is provided in the Recommended Actions section of this CVE to help reduce the risks associated with this vulnerability and to protect their systems.
If there are any further updates regarding mitigations for this vulnerability, this CVE will be updated and customers will be notified. We highly encourage customers to subscribe to Security Update Guide notifications to receive an alert if an update occurs.
Details
A security researcher informed Microsoft of an elevation of privilege vulnerability in Windows Update potentially enabling an attacker with basic user privileges to reintroduce previously mitigated vulnerabilities or circumvent some features of VBS. For exploitation to succeed, an attacker must trick or convince an Administrator or a user with delegated permissions into performing a system restore which inadvertently triggers the vulnerability.
Microsoft has developed a security update to mitigate this threat which was made available October 08, 2024 and is provided in the Security Updates table of this CVE for customers to download. Note: Depending on your version of Windows, addi

New Windows Driver Signature bypass allows kernel rootkit installs

## New Windows Driver Signature bypass allows kernel rootkit installs
## Bill Toulas
Attackers can downgrade Windows kernel components to bypass security features such as Driver Signature Enforcement and deploy rootkits on fully patched systems.
This is possible by taking control of the Windows Update process to introduce outdated, vulnerable software components on an up-to-date machine without the operating system changing the fully patched status.
## Downgrading Windows
SafeBreach security researcher Alon Leviev reported the update takeover issue but Microsoft dismissed it saying that it did not cross a defined security boundary, although was possible by gaining kernel code execution as an administrator.

Leviev has also shared multiple usage examples that allow downgrading the Hyper-V hypervisor (to a two-year-old version), Windows Kernel, the NTFS driver, and the Filter Manager driver (to their base versions), and other Windows components and previously applied security patches.
"You can use it to take over Windows Updates to downgrade and expose past vulnerabilities sourced in DLLs, drivers, the NT kernel, the Secure Kernel, the Hypervisor, IUM trustlets and more," SafeBreach security researcher Alon Leviev explained .
"Other than custom downgrades, Windows Downdate provides easy to use usage examples of reverting patches for CVE-2021-27090, CVE-2022-34709, CVE-2023-21768 and PPLFault, as well as examples fo

Leviev discovered that the Windows update process could be compromised to downgrade critical OS components, including dynamic link libraries (DLLs) and the NT Kernel. Even though all of these components were now out of date, when checking with Windows Update, the OS reported that it was fully updated, with recovery and scanning tools unable to detect any issues.
By exploiting the zero-day vulnerabilities, he could also downgrade Credential Guard's Secure Kernel and Isolated User Mode Process and Hyper-V's hypervisor to expose past privilege escalation vulnerabilities.
