The remote host is affected by a denial of service vulnerability.


According to its self-reported version, the remote Cisco Unified Communications Manager (CUCM) device insufficiently limits the rate of traffic on certain UDP ports, allowing a remote attacker to cause a denial of service condition by sending UDP packets at a high rate.


For Cisco Unified Communications Manager (CUCM) 8.5(x), upgrade to version 8.5(1)su6 or later. For 8.6(x), upgrade to 8.6(2a)su3 or later. For 9.x, upgrade to 9.1(2) or later.
