The second vulnerability (CVE-2023-6549) could allow an attacker to perform a denial of service attack on the equipment. The equipment should be configured as: Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) OR AAAvirtualserver.

Attention that version 12.1 of the products is no longer supported (EOL) and is explicitly stated to be vulnerable!


It is recommended to test and install the following versions as soon as possible:
