تتعلق المشكلة بعدم كفاية التحقق من صحة المدخلات في «منطقة الأمان القائمة على المحاكاة الافتراضية» (VBS) في أنظمة التشغيل Microsoft Windows. وقد يتيح ذلك للمهاجم رفع مستوى امتيازاته.

The issue is related to an elevation of privilege vulnerability in the Virtualization-Based Security (VBS) Enclave of Microsoft Windows operating systems. This vulnerability is associated with deficiencies in the authentication procedure. Exploitation of the vulnerability may allow an attacker to elevate their privileges.

The issue is related to insufficient access restrictions in the Windows AppContainer isolated environment, allowing an attacker to bypass security restrictions and elevate their privileges. An elevation-of-privilege vulnerability exists, enabling attackers to affect the system.

The Dell `dbutil 2 3.sys` driver contains an insufficient access control vulnerability. This issue allows a local authenticated user to escalate privileges, cause a denial of service, or disclose protected information. In real-world incidents, the Lazarus group exploited this flaw using a Bring Your Own Vulnerable Driver (BYOVD) technique—where a legitimate but vulnerable driver is installed on the target system—to deploy the FudModule rootkit. This allowed the attackers to read and write kernel memory, effectively disabling multiple Windows security monitoring mechanisms to execute commands with kernel-level privileges. The campaign targeted individuals in the aerospace industry in the Netherlands and political journalists in Belgium via phishing emails disguised as job offers from Amazon.

Name of the Vulnerable Software and Affected Versions: Windows (affected versions not specified) Description: An elevation of privilege issue exists due to the Windows kernel-mode driver's failure to properly handle objects in memory. This could allow an attacker to run arbitrary code in kernel mode, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights. To exploit this, an attacker must first log on to the system and then run a specially crafted application. The issue is addressed by correcting how the Windows kernel-mode driver handles objects in memory. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

An information disclosure issue exists due to improper initialization of objects in memory by the Remote Procedure Call runtime. This could allow an attacker to disclose protected information using a specially crafted application. The estimated number of potentially affected devices worldwide is not specified. Details about real-world incidents where this issue was exploited are not provided.

The issue is related to insecure privilege management in the Windows kernel, allowing an attacker to disclose protected information using a specially crafted application. This could potentially lead to a Kernel Address Space Layout Randomization (KASLR) bypass.

An information disclosure issue exists due to the Windows Audio Service's failure to properly handle objects in memory. This could allow an attacker to obtain access to protected information in the memory of a privileged process.

The issue exists due to improper handling of objects in memory by a component of the Windows operating system, specifically related to DirectX. This can allow an attacker to elevate their privileges and execute arbitrary code in kernel mode using a specially crafted application. An elevation-of-privilege issue allows attackers to affect the system.

The issue arises from the Windows kernel's improper handling of objects in memory, leading to an information disclosure. This could allow attackers to obtain sensitive information and affect the system.

A security feature bypass exists when Windows incorrectly validates kernel driver signatures. This issue allows attackers to affect the system.

Name of the Vulnerable Software and Affected Versions: Windows 10 versions 1607, 1703, and 1709 Windows Server 2016 Windows Server, version 1709 Description: The issue is related to how objects in memory are handled, allowing an elevation of privilege. This could potentially allow attackers to affect the system. Recommendations: For Windows 10 versions 1607, 1703, and 1709, update to a version that includes the fix for this issue. For Windows Server 2016 and Windows Server, version 1709, apply the necessary patch or update to resolve the elevation of privilege vulnerability. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

A memory leak in the Local RPC (LRPC) server implementation allows remote attackers to cause a denial of service (memory consumption) and bypass the ASLR protection mechanism via a crafted client that sends messages with an invalid data view. The issue is related to the LRPC server not freeing messages from clients that have attached data, which is not expected for the message type. This enables a client to fill up the server's address space with such messages.

The issue allows local users to gain privileges via a crafted application. An elevation of privilege exists in the Client/Server Run-time Subsystem (CSRSS), enabling arbitrary code to be executed in the context of another process. If the process runs with administrator privileges, an attacker could install programs, view, change, or delete data, or create new accounts with full user rights.
