Title
Certificate Validation Bypass in VPN Site-to-Site Connections Using IKEv1
Summary
A weakness in the certificate validation logic of the deprecated IKEv1 key exchange may allow an unauthenticated attacker positioned as a man-in-the-middle to bypass certificate validation in VPN site-to-site connections that use certificate-based authentication.

Title
SQL injection issue in UserCheck Portal when DLP Software Blade is active
Summary
When the DLP is active, the UserCheck Web Portal contains an input-handling issue in the UserChoice flow. Under specific conditions, an attacker who can access the UserCheck Ask page could attempt to manipulate the Security Gateway's stored DLP/UserCheck incident information. This could lead to disruptions such as loss of stored incident entries, incorrect handling of pending approvals, or resource impact if the issue is abused repeatedly.
Exposure is reduced if the UserCheck Portal is not accessible from untrusted networks.

Title
VPN service may restart unexpectedly when processing IKE traffic over NAT-T 4500/UDP
Summary
The Security Gateway does not correctly validate a length value in certain IKE packets when NAT-T is used (4500/UDP). As a result, a specially crafted or malformed packet can cause the VPN processing service to terminate unexpectedly, leading to denial of service (temporary interruption of VPN negotiations/traffic).
