CVE Title: Windows Hyper-V Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. Why is Attack Complexity marked as High for this vulnerability? Successful exploitation of this vulnerability requires an attacker to win a race condition. Why is Scope marked as Changed for this vulnerability? Successful exploitation of this vulnerability would allow a Hyper-V guest to affect the functionality of the Hyper-V host. Mitigations: None Workarounds: None Revision: 1.0 2022-04-12T07:00:00 Information published. |

CVE Title: Windows Hyper-V Remote Code Execution Vulnerability
CVSS: CVSS:3.1 8.8/7.7
FAQ: According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. How could an attacker exploit this vulnerability? To exploit this vulnerability, an attacker could run a specially crafted application on a Hyper-V guest that could cause the Hyper-V host operating system to execute arbitrary code. Why is Scope marked as Changed for this vulnerability? Successful exploitation of this vulnerability would allow a Hyper-V guest to affect the functionality of the Hyper-V host. Mitigations: None Workarounds: None Revision: 1.0 2022-04-12T07:00:00 Information published. |

CVE Title: Microsoft Excel Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: Is the Preview Pane an attack vector for this vulnerability? No, the Preview Pane is not an attack vector. According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. Mitigations: None Workarounds: None Revision: 1.0 2022-04-12T07:00:00 Information published. |

CVE Title: Windows Kerberos Remote Code Execution Vulnerability
CVSS: CVSS:3.1 8.1/7.1
FAQ: According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. Why is Attack Complexity marked as High for this vulnerability? Successful exploitation of this vulnerability requires an attacker to gather information specific to the environment of the targeted component. How do I know if my system is affected by this vulnerability? For systems running Remote Desktop Connection, the server is secure by default. Systems are vulnerable when an administrator has enabled Restricted Admin or Windows Defender Remote Credential Guard on the remote host by using the Registry key setting (DWORD value named "DisableRestrictedAdmin") as outlined in Protect Remote Desktop credentials with Windows Defender Remote Credential Guard.

CVE Title: Microsoft Defender Denial of Service Vulnerability
CVSS: CVSS:3.1 5.5/4.8
FAQ:
See Manage Updates Baselines Microsoft Defender Antivirus for more information. Microsoft Defender is disabled in my environment, why are vulnerability scanners showing that I am vulnerable to this issue? Vulnerability scanners are looking for specific binaries and version numbers on devices. Microsoft Defender files are still on disk even when disabled. Systems that have disabled Microsoft Defender are not in an exploitable state. Why is no action required to install this update? In response to a constantly changing threat landscape, Microsoft frequently updates malware definitions and the Microsoft Malware Protection Engine. In order to be effective in helping protect against new and prevalent threats, antimalware software must be kept up to date with these updates in a timely manner. For enterprise deployments as well as end users, the default configuration in Microsoft antimalware software helps ensure that malware definitions and the Microsoft Malware Protection Engine are kept up to date automatically. Product documentation also recommends that products are configured for automatic updating. Best practices recommend that customers regularly verify whether software distribution, such as the automatic deployment of Microsoft Malware Protection Engine updates and malware definitions, is working as expected in their environment. How often are the Microsoft Malware Protection Engine and malware definitions updated? Microsoft typically releases an update for the Microsoft Malware Protection Engine once a month or as needed to protect against new threats. Microsoft also typically updates the malware definitions three times daily and can increase the frequency when needed. Depending on which Microsoft antimalware software is used and how it is configured, the software may search for engine and definition updates every day when connected to the Internet, up to multiple times daily. Customers can also choose to manually check for updates at any time. What is the Microsoft Malware Protection Engine? The Microsoft Malware Protection Engine, mpengine.dll, provides the scanning, detection, and cleaning capabilities for Microsoft antivirus and antispyware software. Windows Defender uses the Microsoft Malware Protection Engine. On which products is Defender installed and active by default? Defender runs on all supported version of Windows. Are there other products that use the Microsoft Malware Protection Engine? Yes, Microsoft System Center Endpoint Protection, Microsoft System Center 2012 R2 Endpoint Protection, Microsoft System Center 2012 Endpoint Protection and Microsoft Security Essentials. Does this update contain any additional security-related changes to functionality? Yes. In addition to the changes that are listed for this vulnerability, this update includes defense-in-depth updates to help improve security-related features. Suggested ActionsVerify that the update is installed Customers should verify that the latest version of the Microsoft Malware Protection Engine and definition updates are being actively downloaded and installed for their Microsoft antimalware products.

CVE Title: Microsoft Excel Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: Is the Preview Pane an attack vector for this vulnerability? No, the Preview Pane is not an attack vector. According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.

CVE Title: Windows Fax Compose Form Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: In what scenarios is my computer vulnerable? For Windows 11 and Windows 10 the FAX service is not installed by default. To exploit this vulnerability, the Windows Fax and Scan feature needs to be enabled, and the Fax service needs to be running. Systems that do not have the Fax service running are not vulnerable. How can I verify whether the Fax service is running?
According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. According to the CVSS, User Interaction is Required. What interaction would the user have to do? Exploitation of the vulnerability requires that a user employ a specially crafted malicious contact record to send a FAX.

CVE Title: Windows Fax Compose Form Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: In what scenarios is my computer vulnerable? For Windows 11 and Windows 10 the FAX service is not installed by default. To exploit this vulnerability, the Windows Fax and Scan feature needs to be enabled, and the Fax service needs to be running. Systems that do not have the Fax service running are not vulnerable. How can I verify whether the Fax service is running?
According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. According to the CVSS, User Interaction is Required. What interaction would the user have to do? Exploitation of the vulnerability requires that a user employ a specially crafted malicious contact record to send a FAX.

CVE Title: HEVC Video Extensions Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. My system is in a disconnected environment; is it vulnerable? Customers using the Volume Licensing Servicing Center can get this update through their organizations. How can I check if the update is installed? If your device manufacturer preinstalled this app, package versions 1.0.50361.0 and later contain this update. If you purchased this app from the Microsoft Store, package versions 1.0.50362.0 and later contain this update. You can check the package version in PowerShell:

CVE Title: Windows Hyper-V Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. Why is Attack Complexity marked as High for this vulnerability? Successful exploitation of this vulnerability requires an attacker to win a race condition. Why is Scope marked as Changed for this vulnerability? Successful exploitation of this vulnerability would allow a Hyper-V guest to affect the functionality of the Hyper-V host.

CVE Title: Windows Direct Show - Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.0/6.1
FAQ: According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. Why is Attack Complexity marked as High for this vulnerability? Successful exploitation of this vulnerability requires an attacker to gather information specific to the environment of the targeted component.

CVE Title: Windows DNS Server Remote Code Execution Vulnerability
CVSS: CVSS:3.1 6.6/5.8
FAQ: Why is Attack Complexity marked as High for this vulnerability? Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment. How could an attacker exploit this vulnerability? In a network-based attack an attacker would need to have the privileges to query the Domain Name Service (DNS). If the timing of DNS queries is perfect, the attacker could execute code remotely on the target server. According the CVSS score, privileges required is set to High. In this case, what does that mean? To exploit this vulnerability, the attacker or targeted user would need specific elevated privileges. As is best practice, regular validation and audits of administrative groups should be conducted. Mitigations: None Workarounds: None Revision: 1.0 2022-04-12T08:00:00 Information published. |

CVE Title: Windows Graphics Component Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer. Mitigations: None Workarounds: None Revision: 1.0 2022-04-12T07:00:00 Information published. |
