TITLE

Cisco NX-OS Software input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-014545

DESCRIPTION

A vulnerability in the Precision Time Protocol (PTP) feature of Cisco Nexus 5500, 5600, and 6000 Series Switches running Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of protection against PTP frame flood attacks. An attacker could exploit this vulnerability by sending large streams of malicious IPv4 or IPv6 PTP traffic to the affected device. A successful exploit could allow the attacker to cause a DoS condition, impacting the traffic passing through the device. Cisco NX-OS The software contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Cisco NX-OS is a network operating system for Cisco Nexus Series Ethernet Switches and MDS Series Fibre Channel Storage Area Network Switches. This issue is being tracked by Cisco bug ID CSCvg21830. NX-OS Software is a data center-level operating system software used by a set of switches running on it
