fastjson blacklist

背景

fastjson 在1.2.42开始，把原本明文的黑名单改成了哈希过的黑名单，防止安全研究者对其进行研究。在 https://github.com/alibaba/fastjson/commit/eebea031d4d6f0a079c3d26845d96ad50c3aaccd 这次commit中体现出来。

-     private String[] denyList = "bsh,com.mchange,com.sun.,java.lang.Thread,java.net.Socket,java.rmi,javax.xml,org.apache.bcel,org.apache.commons.beanutils,org.apache.commons.collections.Transformer,org.apache.commons.collections.functors,org.apache.commons.collections4.comparators,org.apache.commons.fileupload,org.apache.myfaces.context.servlet,org.apache.tomcat,org.apache.wicket.util,org.apache.xalan,org.codehaus.groovy.runtime,org.hibernate,org.jboss,org.mozilla.javascript,org.python.core,org.springframework".split(",");

+        denyHashCodes = new long[]{
+                -8720046426850100497L,
+                 ......
+                8838294710098435315L
+        };

fastjson 在1.2.61开始，在https://github.com/alibaba/fastjson/commit/d1c0dff9a33d49e6e7b98a4063da01bbc9325a38中，把黑名单从十进制数变成了十六进制数，可能是为了防止安全研究者进行搜索，恕我直言有点可笑。

        denyHashCodes = new long[]{
-                -8720046426850100497L,
-                -8165637398350707645L,
-                -8109300701639721088L,

+                0x86fc2bf9beaf7aefL,
+                0x8eadd40cb2a94443L,
+                0x8f75f9fa0df03f80L,

fastjson 在1.2.62开始，https://github.com/alibaba/fastjson/commit/014444e6c62329ec7878bb6b0c6b28c3f516c54e中，从小写改成了大写，可能是为了规范吧。

本git只记录十进制和小写的十六进制数，不记录大写的十六进制数。

网上没找到类似的仓库，为了弄清楚每个hash到底对应的是什么，就写了个小轮子，跑一下这些case，列出来。

功能

public class Main {
    public static void main(String[] args) throws IOException {
        // 功能1：完善已知列表
        // 使用指定的class去完善
        BreakerUtils.completeDatabase(new String[]{"org.apache.ibatis.datasource.jndi.JndiDataSourceFactory"});
        // 使用指定的jar去完善
        BreakerUtils.completeDatabase(new File("C:\\Users\\leadroyal\\.gradle\\caches\\modules-2\\files-2.1\\com.alibaba\\fastjson\\1.2.24\\a2b82688715ee16d874d90229d204daf3efcac8e\\fastjson-1.2.24.jar"));
        // 使用指定的目录去完善
        BreakerUtils.completeDatabase(new File("C:\\Users\\leadroyal\\.gradle\\caches\\modules-2\\files-2.1\\"), true);


        // 功能2：输入版本号，输出已知和未知的列表
        BreakerUtils.listDatabase(1242);
        BreakerUtils.listDatabase();

        // 功能3：输入classname，输出被ban情况
        BreakerUtils.isBanned("org.apache.ibatis.datasource.jndi.JndiDataSourceFactory");
    }
}

如何贡献

• 如果您是maven/gradle用户的话，本地会缓存很多jar包，可以使用扫目录的方式把所有的代码都扫一遍，很方便，可能会扫出有用的东西

• 直接修改src/java/com/leadroyal/breaker/data代码，并且修改readme，提交pull request就行。
