Cisco Security Advisory: Multiple Cisco Products Disk Utilization Denial of Service Vulnerability
Advisory ID: cisco-sa-20180606-diskdos
For Public Release: 2018 June 6 16:00 GMT
Last Updated: 2018 June 6 16:00 GMT
CVE ID(s): CVE-2017-6779
CVSS Score v(3): 8.6 CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
Multiple Cisco products are affected by a vulnerability in local file management for certain system log files of Cisco collaboration products that could allow an unauthenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition.
The vulnerability occurs because a certain system log file does not have a maximum size restriction. Therefore, the file is allowed to consume the majority of available disk space on the appliance. An attacker could exploit this vulnerability by sending crafted remote connection requests to the appliance. Successful exploitation could allow the attacker to increase the size of a system log file so that it consumes most of the disk space. The lack of available disk space could lead to a DoS condition in which the application functions could operate abnormally, making the appliance unstable.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
