Description
This security bulletin contains information about 2 vulnerabilities.
1) Improper Certificate Validation (CVE-ID: CVE-2026-50752)
CWE-ID: CWE-295 - Improper Certificate Validation
CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to conduct a man-in-the-middle attack.
The vulnerability exists due to improper certificate validation in the IKEv1 key exchange certificate validation logic when establishing a VPN site-to-site connection using certificate-based authentication. A remote attacker can present a crafted certificate to conduct a man-in-the-middle attack.
The issue applies only to VPN site-to-site configurations that use IKEv1 with certificate-based authentication, and does not affect pre-shared key authentication, Dynamic IP gateways, or Large Scale VPN communities.
2) Improper authentication (CVE-ID: CVE-2026-50751) Exploited
CWE-ID: CWE-287 - Improper Authentication
CVSSv4: 7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N]
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to a logic error in the Remote Access and Mobile Access certificate validation during deprecated IKEv1 key exchange. A remote attacker can establish a remote access VPN connection without a valid user password and gain access to network resources available to authenticated users.
Note, the vulnerability is being actively exploited in the wild.
