Fortinet 又出現漏洞
Fortinet addressed a critical buffer underwrite (‘buffer underflow’) vulnerability, tracked as CVE-2023-25610 (CVSS v3 9.3), that resides in the administrative interface in FortiOS and FortiProxy.

如果暫時還沒安排更新計畫，可以先把管理介面鎖定IP或是WAN端口管理介面關閉https http 來緩解一下，建議還是安排更新。
PS: 因為此堆疊區漏洞是存在於 httpsd 的程序，所以無法經由 trust-host 來避免，必須使用 local-in policy 來限制。
