Windows Internet Key Exchange (IKE) Service Extensions Remote Code Execution Vulnerability
Double free in Windows IKE Extension allows an unauthorized attacker to execute code over a network.
Меры по смягчению последствий
The following mitigating factors might be helpful in your situation:
Customers who cannot immediately install the security update can take one of the following actions, depending on their environment:
- Block inbound traffic on UDP ports 500 and 4500 for systems that do not use IKE.
- For systems that require IKE, configure firewall rules to allow inbound traffic on UDP ports 500 and 4500 only from known peer addresses.
These actions reduce the attack surface but do not replace installing the security update when it becomes available.
FAQ
How could an attacker exploit this vulnerability?
