Key Vulnerabilities
Screen out the vulnerabilities with great impact in this update according to product popularity and vulnerability importance. Please pay attention to them:
Windows NTLM Hash Leakage Spoofing Vulnerability (CVE-2024-43451):
Windows NTLM has a hash leak spoofing vulnerability. Attackers induce users to interact with malicious files by misusing MSHTML, such as clicking or right-clicking to view, thus disclosing the user’s NTLMv2 hash. Attackers can use these hashes for authentication. The vulnerability has been publicly disclosed and exploited, with a CVSS score of 6.5.
Official Announcement Link: https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2024-43451
Windows Task Scheduler privilege escalation vulnerability (CVE-2024-49039):
A privilege escalation vulnerability exists in the Windows Task Scheduler, which can be exploited by an authenticated attacker running a special application that enables the attacker to implement container escape from a low-privileged environment and gain higher-privileged access, thereby performing RPC functions typically limited to privileged accounts. The vulnerability has been exploited, with a CVSS score of 8.8.
Official Announcement Link: https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2024-49039
Windows Kerberos Remote Code Execution Vulnerability (CVE-2024-43639):
A remote code execution vulnerability exists in Windows Kerberos, where an unauthenticated attacker can cause the Kerberos proxy to access a specified malicious server by sending an HTTP request due to a number truncation error in Windows Kerberos. Allows the Kerberos agent to improperly parse returned crafted packets, resulting in remote code execution. This vulnerability affects all supported versions of Windows Server and may result in worm-like propagation between systems. CVSS score is 9.8.
Official Announcement Link: https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2024-43639
.NET and Visual Studio Remote Code Execution Vulnerabilities (CVE-2024-43498):
A remote code execution vulnerability exists in .NET and Visual Studio, where an unauthenticated attacker can execute arbitrary code on the target system by sending a specially crafted request to the .NET application or loading a specially crafted file into the desktop application due to type obfuscation errors in .NET and Visual Studio. CVSS score is 9.8.
Official Announcement Link: https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2024-43498
Microsoft Windows VMSwitch privilege escalation vulnerability (CVE-2024-43625):
Microsoft Windows VMSwitch has a privilege escalation vulnerability. Due to the Use-After-Free reuse error of the VmSwitch component in Microsoft Hyper-V, an attacker can send a series of specific network requests to the VMswitch driver to gain SYSTEM privileges of the system. CVSS score is 8.1.
Official Announcement Link: https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2024-43625
Active Directory Certificate Service Permission Escalation Vulnerability (CVE-2024-49019):
The Active Directory certificate service has a privilege escalation vulnerability. Due to an error in processing authentication requests in the Active Directory certificate service, local users can bypass authentication by misusing the built-in default version certificate template to obtain domain administrator permissions. The vulnerability has been publicly disclosed, with a CVSS score of 8.8.
Official Announcement Link: https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2024-49019
Microsoft Exchange Server Spoofing Vulnerability (CVE-2024-49040):
Microsoft Exchange Server has a spoofing vulnerability where an attacker can forge the sender’s email address in an email sent to a local recipient due to improper processing of user-provided data. The vulnerability has been publicly disclosed, with a CVSS score of 7.5.
Official Announcement Link: https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2024-49040
