suexec违反政策:这些家伙在做什么？

Question

刚刚开始负责一个新客户的网站。操作系统是Linux。他们在文档根目录下有一个cgi-bin目录。

我查看了我的error.log，找出了一个脚本的问题，并发现了一些试图访问使用dis的Perl脚本的尝试。我已经删除了整个cgi目录。

问题：

我在哪里可以找到Linux上的suexec日志？它不在/var/log/httpd/suexec_log中。

如果权限设置正确，攻击者如何获得cgi目录列表？

现在cgi已经被移除了，对进一步的行动有什么想法吗？

Answer 1

Linux的味道是什么？尝试/var/ log /apache2/suexec.log，但看起来suexec (Apache)没有写入日志文件的权限。似乎是个寻找易受攻击脚本的机器人。
