CVE-2008-2062: The Real-Time Information Server (RIS) Data Collector service in Cisco Unified Communications Manager (CUCM...

Security readout for executives and security teams

CVE-2008-2062 is an authentication bypass in Cisco Unified Communications Manager’s RIS Data Collector service. An unauthenticated remote user could directly connect to the service and view cluster configuration information and statistics. This is mainly an information-disclosure risk, but exposed voice infrastructure can reveal operational details useful for later attacks. Exposure is most likely in legacy CUCM 4.2 or 4.3 deployments where the RIS Data Collector service is reachable over TCP from untrusted or broad internal networks. Prioritize if legacy CUCM remains in service or management services are broadly reachable. This is not described as code execution, but it can expose voice-cluster details that increase attacker knowledge. Mitigation focus: Upgrade affected CUCM 4.2 systems to 4.2(3)SR4 or later.; Upgrade affected CUCM 4.3 systems to 4.3(2)SR1 or later.; Consult Cisco’s advisory for supported remediation and operational caveats..
