利用判断
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 Client是美国Apache基金会开源的一款服务端软件产品。 Apache Storm Client 3.0.0版本至3.1.0之前版本存在授权问题漏洞，该漏洞源于SimpleACLAuthorizer在nimbus.users为空时提前返回，未评估nimbus.groups，导致仅配置组访问限制时访问控制未生效，可能使已认证用户执行所有用户级操作，包括submitTopology、beginFileUpload和getNimbusConf。

Vulnerability Title
Apache Storm Client: Authorization Bypass When nimbus.groups Is Configured Without nimbus.users
来源: CVE Program / CVE List V5
Vulnerability Description
Description
`SimpleACLAuthorizer` evaluated the user-level command set by returning early when `nimbus.users` was empty,
before `nimbus.groups` was considered. An operator who restricted cluster access by group alone, leaving
`nimbus.users` unset, therefore received no restriction at all: every authenticated principal was permitted
every user-level operation, including `submitTopology`, `beginFileUpload` and `getNimbusConf`.
`docs/SECURITY.md` presents `nimbus.groups` as a supported way to lock down a cluster, so a deployment
following the documentation could believe it was restricted while it was not. The failure is silent; nothing
in the logs or the configuration indicates that the group list is being ignored.
Both lists left empty continues to mean that no restriction is configured, which is the shipped default and
is unchanged.
Mitigation
Upgrade to 3.1.0, where `nimbus.groups` is evaluated whether or not `nimbus.users` is set.
Users who cannot upgrade immediately should additionally populate `nimbus.users` with the intended
principals, since a non-empty user list causes the group list to be evaluated on affected versions.
Operators should review Nimbus access logs for operations by principals outside the intended groups.
Note that after upgrading, a cluster configured with `nimbus.groups` alone becomes restrictive for the first
time. This includes `NimbusClient`, which calls `getLeader` on every connection, so clients outside the
configured groups will begin to be refused.
