尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
Apache Storm Nimbus是美国Apache基金会开源的一个负责分布式实时计算集群任务调度与状态监控的主控服务。 Apache Storm Nimbus 3.0.0版本至3.1.0之前版本和Apache Storm Client 3.0.0版本至3.1.0之前版本存在安全漏洞，该漏洞源于配置ZooKeeper身份验证时，Storm在拓扑配置中保留 ，Nimbus将其提供给具有只读拓扑权限的调用者，且提交客户端和SASL

Vulnerability Title
Apache Storm Nimbus, Apache Storm Client: Disclosure of the Topology ZooKeeper Credential to Read-Only Users and to Logs
来源: CVE Program / CVE List V5
Vulnerability Description
Description
When ZooKeeper authentication is configured, Storm deliberately retains
`storm.zookeeper.topology.auth.payload` in the topology configuration, because workers need it. Nimbus then
served that configuration verbatim to any caller holding read-only topology permissions, so a user whose
only grant was the ability to view a topology received its ZooKeeper credential.
That credential is not read-only. The cluster state implementation uses write-capable ACLs for worker
heartbeats, backpressure and error state, so a recipient can forge or remove that state for the topology
concerned. It is not a write credential on assignments.
The same advisory covers the submission client, which logged the generated payload at INFO on every
submission that generated one, and the SASL handlers, which logged it at DEBUG. The credential therefore
also reached any log aggregation or support bundle collected from the cluster.
Mitigation
Upgrade to 3.1.0, where the payload is removed from the configuration served to read-only callers and is no
longer written to logs.
Users who cannot upgrade immediately should rotate `storm.zookeeper.topology.auth.payload` for existing
topologies, review retained logs and support bundles for the value, and restrict read-only topology
permissions to trusted principals.
