dubbo-rce's Issues

CVE-2023-23638项目跑起来，没有触发漏洞

您好，大佬，我运行这个项目，没有触发漏洞阿

你好CVE-2023-23638仓库代码运行请教

X1r0z，您好：
我使用仓库代码存在一些报错无法解决，希望您能够指导一下

运行环境

jdk 17
- vm options :--add-opens java.base/java.math=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED -Ddubbo.hessian.allowNonSerializable=true
zookeeper-3.7.0
<dubbo.version>3.1.5</dubbo.version>

如果不加--add-opens java.base/java.math=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED
会提示：module java.base does not "opens java.math/lang" to unnamed module @16d04d3d

尝试

zkServer status

$ bin/zkServer status
/usr/local/Cellar/openjdk@17/17.0.3/libexec/openjdk.jdk/Contents/Home/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.

我访问提示faq/4/20提示可能的原因是服务方和调用方的版本不匹配，我到这里就无法继续了，烦请指导～
