## Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in the IKEv2 certificate URL fetching mechanism of PAN-OS. An unauthenticated remote attacker can exploit this by sending specially crafted IKEv2 traffic to a Site-to-Site VPN Gateway. Successful exploitation allows the attacker to force the firewall to initiate network requests to arbitrary destinations or trigger a denial of service (DoS) condition. The vulnerability specifically impacts configurations where IKEv2 is enabled for Site-to-Site VPNs. Patches are available for PAN-OS 10.2, 11.1, 11.2, and 12.1 branches.

## Affected products

- Palo Alto Networks PAN-OS 12.1 < 12.1.4-h5, 12.1 < 12.1.7, 11.2 < 11.2.4-h17, 11.2 < 11.2.7-h13, 11.2 < 11.2.10-h6, 11.2 < 11.2.12, 11.1 < 11.1.4-h33, 11.1 < 11.1.6-h32, 11.1 < 11.1.7-h6, 11.1 < 11.1.10-h25, 11.1 < 11.1.13-h5, 11.1 < 11.1.15, 10.2 < 10.2.7-h34, 10.2 < 10.2.10-h36, 10.2 < 10.2.13-h21, 10.2 < 10.2.16-h7, 10.2 < 10.2.18-h6
