CVE-2024-38063
vulnerability analysis and mitigation

Overview

CVE-2024-38063 is a critical Windows TCP/IP Remote Code Execution Vulnerability affecting Windows systems. The vulnerability was discovered and disclosed by Microsoft, with a CVE ID assigned on June 11, 2024. This critical vulnerability affects multiple Windows versions including Windows 10, Windows 11, and Windows Server versions from 2008 through 2022, particularly systems with IPv6 enabled, which is the default configuration for most modern Windows deployments (Orca Security).

Technical details

The vulnerability stems from an integer underflow issue in the Windows TCP/IP stack's handling of IPv6 packets. When arithmetic subtraction results in a value smaller than the minimum integer limit, it creates an indeterministic state in the application. The vulnerability has received a Critical CVSS v3.1 base score of 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating its severe nature. Microsoft has classified this as CWE-191 (Integer Underflow) (NVD).

Impact

If successfully exploited, this vulnerability allows attackers to execute arbitrary code remotely on affected systems without requiring user interaction. The attacker can gain SYSTEM-level access, potentially leading to complete system compromise, allowing them to execute malicious code, compromise sensitive data, and install malware (Orca Security).

Mitigation and workarounds

Two primary mitigation strategies are recommended: 1) Apply the latest Windows security updates immediately to patch the vulnerability, and 2) If immediate patching is not possible, temporarily disable IPv6, though this should only be considered a short-term solution as it may disrupt network services. Continuous monitoring for unusual IPv6 network traffic is also advised (Orca Security).
