CVE-2018-0157

Ein entfernter, anonymer oder authentisierter Angreifer kann mehrere Schwachstellen in Cisco IOS und Cisco IOS XE ausnutzen, um Daten zu manipulieren, vertrauliche Daten einzusehen, einen Denial of Service Angriff durchzuführen, seine Privilegien zu erweitern, Cross-Site Scripting Angriffe durchzuführen, Sicherheitsmechanismen zu umgehen oder beliebigen Code mit administrativen Privilegien zur Ausführung zu bringen.

A vulnerability in the Zone-Based Firewall code of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a device to reload. The vulnerability is due to the way fragmented packets are handled in the firewall code. An attacker could exploit this vulnerability by sending fragmented IP Version 4 or IP Version 6 packets through an affected device. An exploit could allow the attacker to cause the device to crash, resulting in a denial of service (DoS) condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
