ipeeyoupeewepee

ipeeyoupeewepee 一个针对公网主机（主要是 Cisco 路由器）的扫描与攻击套件，这些主机转发未经认证的 IP-in-IP 和 GRE 协议封装的数据包。 此漏洞被称为“隧道协议的不安全实现”，编号为 CVE-2020-10136 和 CVE-2024-7595。它允许你从受影响的主机发送（但不能接收）任意 IP 数据包。 乍看之下，只能发送不能接收数据包似乎毫无用处。然而，许多受影响的主机位于未实施反向路径过滤的网络中。这意味着你可以利用这些漏洞，在没有缺乏源地址验证（通常称为 IP 头部修改或 IPHM）的主机的情况下，在公网上伪造 IP 地址，从而发起 DNS...

CVE-2026-74478

A flaw was found in the Linux kernel. A remote attacker, by sending specially crafted packets over GRE or L2TPv3 transports, could trigger a use-after-free vulnerability. This occurs in the vectormmsgrx function when a packet's overlay header fails verification, causing the system to attempt to...

CVE-2026-74478

CVE-2026-74478 affects the Linux kernel, specifically the vector_mmsg_rx() path. When a packet is discarded because verify_header() fails, the code previously continued without advancing the slot, leaving a freed skb in the vector and causing a use-after-free in the RX path. The issue can be trig...
