An attacker could exploit this vulnerability by sending crafted, malformed IP packets to an affected device. A successful exploit could allow the attacker to cause an affected device to reload, resulting in a DoS condition.
CVE-2019-12643 1 Cisco 8 4221 Integrated Services Router, 4321 Integrated Services Router, 4331 Integrated Services Router and 5 more 2024-02-28 10.0 HIGH 10.0 CRITICAL
A vulnerability in the Cisco REST API virtual service container for Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass authentication on the managed Cisco IOS XE device. The vulnerability is due to an improper check performed by the area of code that manages the REST API authentication service. An attacker could exploit this vulnerability by submitting malicious HTTP requests to the targeted device. A successful exploit could allow the attacker to obtain the token-id of an authenticated user. This token-id could be used to bypass authentication and execute privileged actions through the interface of the REST API virtual service container on the affected Cisco IOS XE device. The REST API interface is not enabled by default and must be installed and activated separately on IOS XE devices. See the Details section for more information.
CVE-2019-1904 1 Cisco 11 4321 Integrated Services Router, 4331 Integrated Services Router, 4351 Integrated Services Router and 8 more 2024-02-28 6.8 MEDIUM 8.8 HIGH
A vulnerability in the web-based UI (web UI) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web UI on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link.
