Cisco Unified Communications Manager (RIS) Data Collector service information disclosure

cucm-risdatacollector-info-disclosure (43355) The risk level is classified as LowLow Risk

Description:

Cisco Unified Communications Manager (CUCM) could allow a remote attacker to bypass authentication and obtain information, caused by an error in the Real-Time Information Server (RIS) Data Collector service. By connecting directly to the RIS Data Collector service using TCP port 2556, a remote attacker could exploit this vulnerability to gain read-only access to restricted information and obtain the performance statistics and user names of the CUCM cluster.
