Microsoft · Windows · CVE-2024-38063
**Name of the Vulnerable Software and Affected Versions**
Windows versions prior to the fixed version
**Description**
A critical vulnerability in the Windows TCP/IP stack allows for remote code execution through specially crafted IPv6 packets. This zero-click exploit affects all Windows systems with IPv6 enabled and can be exploited remotely without requiring any user interaction. The vulnerability is caused by an integer underflow in the processing of IPv6 options, which can lead to a buffer overflow and arbitrary code execution.
**Recommendations**
To resolve the issue, apply the latest security updates from Microsoft. If immediate patching is not feasible, consider disabling IPv6 on all systems as a temporary mitigation measure. However, note that disabling IPv6 may break certain Windows features, so it is recommended to patch systems as soon as possible. Additionally, conduct a network audit to identify any unauthorized IPv6 traffic and restrict network connectivity to minimize exposure.
