Cisco Unified Communications Manager 9.0 contains a vulnerability that could allow an unauthenticated, remote attacker to poison the Location Bandwidth Manager (LBM) transaction records.
The vulnerability is due to a lack of authentication of the remote LBM Hub node in the Intracluster communication between LBMs. An attacker could exploit this vulnerability by poisoning the LBM transaction records to consume all available bandwidth pools. An exploit could allow the attacker to consume all bandwidth and deny calls.
Cisco Unified Communications Manager contains a vulnerability which could allow an unauthenticated, remote attacker to cause a denial of service condition on the affected device.
