[编程] openssh 的远程漏洞演示代码似乎有问题。

发表于

在 github 上搜一下 CVE-2024-6387 ,出来一堆演示代码。

主流是一个叫 7etsuo-regreSSHion.c 源文件。能编译,但是代码都是错的。

有一个 send_packet 的函数,是发送 ssh2 包。但是 size_t packet_len = len + 5;这句明显是错误的,ssh 协议定义 rfc4253 里,明确写了"The length of the packet in bytes, not including 'mac' or the 'packet_length' field itself.", 这里应该是 len+1, 而不是 len+5 。
