![]() Note that any guest-to-host escape should be taken very seriously. As an authenticated user, the attacker could try to trigger malicious code in the context of the server’s account through a network call. Since the Dynamics NAV opened the port, this could be used to connect with the Windows Communication Foundation (WCF) TCP protocol. This security flaw that could lead to a scope change allows an authenticated attacker to execute code on the host server (underlying operating system) in the context of the service account Dynamics configured to use. This critical vulnerability affects Microsoft Dynamics NAV and Microsoft Dynamics 365 Business Central (On-Premises). This vulnerability has a CVSSv3.1 score of 8.5/10. Users could get emails that look like they are coming from trusted users with malicious attachments, and not many users wouldn’t open them.Įxploitability Assessment: Exploitation Less Likely Microsoft Critical Vulnerability Highlights CVE-2022-41127 | Microsoft Dynamics NAV and Microsoft Dynamics 365 Business Central (On Premises) Remote Code Execution Vulnerability If we mix this bug along with above mention Windows SmartScreen Security Feature Bypass (CVE-2022-44698), it will be very destructive. This could cause a user to mistakenly trust a signed email message as if it came from a legitimate user. ![]() This vulnerability could allow an attacker to appear as a trusted user when they should not be. This security bug is rated as important and a spoofing vulnerability, which we want to emphasize since it relates to email clients. This vulnerability has a CVSSv3.1 score of 7.5/10. Patching this vulnerability is highly recommended.Įxploitability Assessment: Exploitation Detected CVE-2022-44713 | Microsoft Outlook for Mac Spoofing Vulnerability With the significant number of phishing attacks every day depending on users opening malicious files/attachments, these types of protection act as essential means to prevent attacks. ![]() This will result in a limited loss of integrity and availability of security features such as Protected View in Microsoft Office, which rely on MOTW tagging. It removes the MOTW feature from the file or makes it so that the MOTW isn’t recognized by the security features that Microsoft provides and lets you open files without warnings. Simply, a specially crafted file could be constructed to bypass the Mark of the Web (MOTW) defenses mechanism. This vulnerability is rated as Moderate, and it appears to be related to Windows Mark of the Web Security Feature Bypass Vulnerability (CVE-2022-41091) from last month. This vulnerability has a CVSSv3.1 score of 5.4/10.
