受影响:
Cisco Unified CallManager 4.1
Cisco Unified Communications Manager 6.x
Cisco Unified Communications Manager 5.x
Cisco Unified Communications Manager 4.3
Cisco Unified Communications Manager 4.2

不受影响:
Cisco Unified Communications Manager 6.1(2)
Cisco Unified Communications Manager 5.1(3c)
Cisco Unified Communications Manager 4.3(2)SR1
Cisco Unified Communications Manager 4.2(3)SR4

描述:
Cisco Unified Communications Manager(CUCM,之前被称为CallManager)是Cisco IP电话解决方案中的呼叫处理组件。

CUCM的实时信息服务器(RIS)数据收集器服务存在绕过认证,可能导致非授权泄露某些CUCM集群信息。

在正常的操作中,实时监控工具(RTMT)客户端通过认证到基于Web接口的简单对象访问协议(SOAP)收集CUCM集群统计,SOAP接口将认证的连接代理到RIS数据收集器进程。RIS数据收集器服务默认监听于TCP 2556端口,是用户可配置的。如果直接连接到RIS数据收集器进程所监听的端口,就可以绕过认证检查获得对CUCM集群信息的只读访问。可获得的信息包括性能统计、用户名和配置的IP电话,这些信息可能被用于发动进一步的。
