[原文]PF in certain OpenBSD versions, when stateful filtering is enabled, does not limit packets for a session to the original interface, which allows remote attackers to bypass intended packet filters via spoofed packets to other interfaces.

[CNNVD]OpenBSD PF状态跟踪欺骗包漏洞(CNNVD-200412-219)

        OpenBSD PF是OpenBSD系统下实现的包过滤系统。
        OpenBSD PF当状态检测启动时处理包存在问题,远程攻击者可以利用这个漏洞绕过PF的通信过滤。

Loss of Integrity
Exploit Unknown

- 漏洞描述

OpenBSD PF contains a flaw that may allow a malicious user to bypass packet filtering. The issue is triggered when PF fails to limit packets for a session to the original interface, allowing a malicious user to spoof packets to other interfaces. However, the spoofed packets must match an existing state session. It is possible that the flaw may allow an attacker to bypass rulesets resulting in a loss of integrity.
