CVE Title: Windows Authentication Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.5/6.5
FAQ: According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment. According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability? An attacker must already have access and the ability to run code on the target system. This technique does not allow for remote code execution in cases where the attacker does not already have that ability on the target system. Mitigations: None Workarounds: None Revision: 1.0 2023-01-10T08:00:00 Information published. |

CVE Title: Microsoft Cryptographic Services Elevation of Privilege Vulnerability
CVSS: CVSS:3.1 8.8/7.7
FAQ: According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability? A locally authenticated attacker could send specially crafted data to the local CSRSS service to elevate their privileges from AppContainer to SYSTEM. Because the AppContainer environment is considered a defensible security boundary, any process that is able to bypass the boundary is considered a change in Scope. The attacker could then execute code or access resources at a higher integrity level than that of the AppContainer execution environment. Mitigations: None Workarounds: None Revision: 1.0 2023-01-10T08:00:00 Information published. |

CVE Title: Microsoft Office Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? A user needs to be tricked into running malicious files. Are the updates for the Microsoft Office for Mac currently available? The security update for Microsoft Office 2019 for Mac and Microsoft Office LTSC for Mac 2021 are not immediately available. The updates will be released as soon as possible, and when they are available, customers will be notified via a revision to this CVE information. According to the CVSS metric, the attack vector is local (AV:L). 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. The vulnerable endpoint is only available over the local VM interface as all external communication is blocked. This means an attacker needs to execute code from the local machine to exploit the vulnerability. Mitigations: None Workarounds: None Revision: 1.0 2023-01-10T08:00:00 Information published. |

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: Microsoft Exchange Server Spoofing Vulnerability
CVSS: CVSS:3.1 8.0/7.0
FAQ: What type of information could be disclosed by this vulnerability? Exploiting this vulnerability could allow the disclosure of NTLM hashes. According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability? This vulnerability's attack is limited at the protocol level to a logically adjacent topology. This means it cannot simply be done across the internet, but instead needs something specific tied to the target. Good examples would include the same shared physical network (such as Bluetooth or IEEE 802.11), logical network (local IP subnet), or from within a secure or otherwise limited administrative domain (MPLS, secure VPN to an administrative network zone). This is common to many attacks that require man-in-the-middle type setups or that rely on initially gaining a foothold in another environment. According to the CVSS metric, privileges required is low (PR:L). Does the attacker need to be in an authenticated role on the Exchange Server? Yes, the attacker must be authenticated. According to the CVSS metric, successful exploitation of this vulnerability could lead to total loss of availability (A:H)? What does that mean for this vulnerability? If the attack is successful it could lead to a NTLM relay allowing for controls that would be able to block availability of a resource.

CVE Title: 3D Builder Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: According to the CVSS metric, the attack vector is local (AV:L). 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 metric, user interaction is required (UI:R). What interaction would the user have to do? An attacker must send the user a malicious file and convince the user to open said file. Is the update for 3D Builder currently available? The security update for 3D Builder is not immediately available. The update will be released as soon as possible, and when it is available, customers will be notified via a revision to this CVE information. Mitigations: None Workarounds: None Revision: 1.0 2023-01-10T08:00:00 Information published. |

CVE Title: 3D Builder Remote Code Execution Vulnerability
CVSS: CVSS:3.1 7.8/6.8
FAQ: According to the CVSS metric, the attack vector is local (AV:L). 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 metric, user interaction is required (UI:R). What interaction would the user have to do? An attacker must send the user a malicious file and convince the user to open said file. Is the update for 3D Builder currently available? The security update for 3D Builder is not immediately available. The update will be released as soon as possible, and when it is available, customers will be notified via a revision to this CVE information. Mitigations: None Workarounds: None Revision: 1.0 2023-01-10T08:00:00 Information published. |

CVE Title: Azure Service Fabric Container Elevation of Privilege Vulnerability
CVSS: CVSS:3.1 7.0/6.1
FAQ: Which Azure service(s) does this affect? This vulnerability affects Azure Service Fabric clusters and standalone Service Fabric clusters orchestrated by Docker. Only users who implement the Docker app containers can be affected. What privileges could be gained by an attacker who successfully exploited the vulnerability? An attacker who successfully exploited this vulnerability could elevate their privileges and gain control over the Service Fabric cluster. This vulnerability does not allow the attacker to elevate privileges outside of the compromised cluster. According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to first compromise the Service Fabric container and for the targeted environment to be architected in a unique manner. According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability? Any authenticated attacker could trigger this vulnerability. It does not require admin or other elevated privileges. How do I protect myself from this vulnerability? To be protected from this vulnerability customers must perform the following actions:
NOTE: This feature restricts connectivity to the internal Azure platform resource (168.63.129.16). Customers are highly encouraged to review their cluster endpoints and ensure they are not making any calls or requests to 168.63.129.16 prior to enabling this feature to prevent service interruptions. What Service Fabric versions are protected against this vulnerability? The Service Fabric versions listed below provide customers the ability to enable the BlockAccessToWireServer feature flag which will protect against this vulnerability. Customers without auto-update enabled must update their Service Fabric resources as appropriate.
