**Name of the Vulnerable Software and Affected Versions** macOS versions prior to 13.3 macOS Monterey versions prior to 12.6.4 macOS Big Sur versions prior to 11.7.5 iOS versions prior to 16.4 iOS versions prior to 15.7.4 iPadOS versions prior to 16.4 iPadOS versions prior to 15.7.4 **Description** The issue was addressed with improved authentication. A user in a privileged network position may be able to spoof a VPN server that is configured with EAP-only authentication on a device. **Recommendations** For macOS versions prior to 13.3, update to macOS Ventura 13.3. For macOS Monterey versions prior to 12.6.4, update to macOS Monterey 12.6.4. For macOS Big Sur versions prior to 11.7.5, update to macOS Big Sur 11.7.5. For iOS versions prior to 16.4, update to iOS 16.4. For iOS versions prior to 15.7.4, update to iOS 15.7.4. For iPadOS versions prior to 16.4, update to iPadOS 16.4. For iPadOS versions prior to 15.7.4, update to iPadOS 15.7.4.

**Name of the Vulnerable Software and Affected Versions** strongSwan versions prior to 5.9.5 **Description** A malicious responder can send an EAP-Success message too early without actually authenticating the client. This can occur even without server authentication in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2. **Recommendations** For strongSwan versions prior to 5.9.5, update to version 5.9.5 or later to resolve the issue. As a temporary workaround, consider implementing additional authentication measures to verify the authenticity of EAP-Success messages. Restrict access to IKEv2 authentication to minimize the risk of exploitation.
