CVE-2018-15396 Information

Description

A vulnerability in the Bulk Administration Tool (BAT) for Cisco Unity Connection could allow an authenticated remote attacker to cause high disk utilization resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software does not restrict the maximum size of certain files that can be written to disk. An attacker who has valid administrator credentials for an affected system could exploit this vulnerability by sending a crafted remote connection request to an affected system. A successful exploit could allow the attacker to write a file that consumes most of the available disk space on the system causing application functions to operate abnormally and leading to a DoS condition.
