Stay Alert

微软 has just released a critical security update to address a severe vulnerability (CVE-2024-38063) in the Windows TCP/IP stack. This flaw, with a maximum severity rating of Critical and a CVSSv3 score of 9.8, affects all supported Windows and Windows Server versions, including Server Core installations.

Why This Matters:

• Remote Exploitation: Attackers can exploit this vulnerability by sending specially crafted IPv6 packets, without any user interaction, making this a “0-click” exploit.
• Critical Risk: Successful exploitation could allow an attacker to execute arbitrary code with SYSTEM privileges, giving them full control over the affected system.
• Widespread Impact: This vulnerability affects all supported versions of Windows and Windows Server.

Immediate Actions to Take:

1. Apply the Latest Security Patches: Microsoft has released patches for all affected systems. Update immediately to secure your environment.
2. Disable IPv6 If Not Required: As the exploit only targets IPv6 packets, consider disabling IPv6 to mitigate this risk further.
3. Monitor Your Network: Be vigilant for any suspicious IPv6 traffic or network activity.

Prioritize Internet-Facing Systems: Ensure that these systems are patched first, as they are most vulnerable.
