TITLE

Cisco StarOS Input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-008203

DESCRIPTION

A vulnerability in the reassembly logic for fragmented IPv4 packets of Cisco StarOS running on virtual platforms could allow an unauthenticated, remote attacker to trigger a reload of the npusim process, resulting in a denial of service (DoS) condition. There are four instances of the npusim process running per Service Function (SF) instance, each handling a subset of all traffic flowing across the device. It is possible to trigger a reload of all four instances of the npusim process around the same time. The vulnerability is due to improper handling of fragmented IPv4 packets containing options. An attacker could exploit this vulnerability by sending a malicious IPv4 packet across an affected device. An exploit could allow the attacker to trigger a restart of the npusim process, which will result in all traffic queued toward this instance of the npusim process to be dropped while the process is restarting. The npusim process typically restarts within less than a second. This vulnerability affects: Cisco Virtualized Packet Core-Single Instance (VPC-SI), Cisco Virtualized Packet Core-Distributed Instance (VPC-DI), Cisco Ultra Packet Core (UPC). Cisco Bug IDs: CSCvh29613. Cisco StarOS Contains an input validation vulnerability. Vendors have confirmed this vulnerability Bug ID CSCvh29613 It is released as.Service operation interruption (DoS) There is a possibility of being put into a state. Cisco StarOS for ASR 5000 Series Routers is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition. production version. Cisco StarOS is one of the virtualized operating systems
