A vulnerability in the web UI feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system through the web UI.
This vulnerability is due to incorrectly accepting configuration changes through the HTTP GET method. An attacker could exploit this vulnerability by persuading a currently authenticated administrator to follow a crafted link. A successful exploit could allow the attacker to change the configuration of the affected device.

A vulnerability in the Resource Reservation Protocol (RSVP) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition.
This vulnerability is due to a buffer overflow when processing crafted RSVP packets. An attacker could exploit this vulnerability by sending RSVP traffic to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

A vulnerability in the IKEv1 fragmentation code of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a heap underflow, resulting in an affected device reloading.
This vulnerability exists because crafted, fragmented IKEv1 packets are not properly reassembled. An attacker could exploit this vulnerability by sending crafted UDP packets to an affected system. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition.
Note: Only traffic that is directed to the affected system can be used to exploit this vulnerability. This vulnerability can be triggered by IPv4 and IPv6 traffic..

A vulnerability in the data model interface (DMI) services of Cisco IOS XE Software could allow an unauthenticated, remote attacker to access resources that should have been protected by a configured IPv4 access control list (ACL).
This vulnerability is due to improper handling of error conditions when a successfully authorized device administrator updates an IPv4 ACL using the NETCONF or RESTCONF protocol, and the update would reorder access control entries (ACEs) in the updated ACL. An attacker could exploit this vulnerability by accessing resources that should have been protected across an affected device.

A vulnerability in the handling of encrypted wireless frames of Cisco Aironet Access Point (AP) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on the affected device.
This vulnerability is due to incomplete cleanup of resources when dropping certain malformed frames. An attacker could exploit this vulnerability by connecting as a wireless client to an affected AP and sending specific malformed frames over the wireless connection. A successful exploit could allow the attacker to cause degradation of service to other clients, which could potentially lead to a complete DoS condition.

A vulnerability in the Unified Threat Defense (UTD) configuration CLI of Cisco IOS XE Software could allow an authenticated, local attacker to execute arbitrary commands as root on the underlying host operating system. To exploit this vulnerability, an attacker must have level 15 privileges on the affected device.
This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by submitting a crafted CLI command to an affected device. A successful exploit could allow the attacker to execute arbitrary commands as root on the underlying operating system.

A vulnerability in auxiliary asynchronous port (AUX) functions of Cisco IOS XE Software could allow an authenticated, local attacker to cause an affected device to reload or stop responding.
This vulnerability is due to the incorrect handling of specific ingress traffic when flow control hardware is enabled on the AUX port. An attacker could exploit this vulnerability by reverse telnetting to the AUX port and sending specific data after connecting. A successful exploit could allow the attacker to cause the device to reset or stop responding, resulting in a denial of service (DoS) condition.

A vulnerability in the IPv4 Software-Defined Access (SD-Access) fabric edge node feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause high CPU utilization and stop all traffic processing, resulting in a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper handling of certain IPv4 packets. An attacker could exploit this vulnerability by sending certain IPv4 packets to an affected device. A successful exploit could allow the attacker to cause the device to exhaust CPU resources and stop processing traffic, resulting in a DoS condition.

A vulnerability in the IP packet processing of Cisco Access Point (AP) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to insufficient input validation of certain IPv4 packets. An attacker could exploit this vulnerability by sending a crafted IPv4 packet either to or through an affected device. A successful exploit could allow the attacker to cause an affected device to reload unexpectedly, resulting in a DoS condition. To successfully exploit this vulnerability, the attacker does not need to be associated with the affected AP. This vulnerability cannot be exploited by sending IPv6 packets.

A vulnerability in the NETCONF feature of Cisco IOS XE Software could allow an authenticated, remote attacker to elevate privileges to root on an affected device.
This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted input over NETCONF to an affected device. A successful exploit could allow the attacker to elevate privileges from Administrator to root.
