A vulnerability in the RADIUS message processing feature of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain RADIUS requests. An attacker could exploit this vulnerability by sending a specific authentication request to a network access device (NAD) that uses Cisco ISE for authentication, authorization, and accounting (AAA). A successful exploit could allow the attacker to cause Cisco ISE to reload.Show less

A vulnerability in the API of Cisco Unified Intelligence Center could allow an authenticated, remote attacker to perform a horizontal privilege escalation attack on an affected system. This vulnerability is due to insufficient validation of user-supplied parameters in API requests.

A vulnerability in the Network Configuration Access Control Module (NACM) of Cisco IOS XE Software could allow an authenticated, remote attacker to obtain unauthorized read access to configuration or operational data. This vulnerability exists because a subtle change in inner API call behavior causes results to be filtered incorrectly. An attacker could exploit this vulnerability by using either NETCONF, RESTCONF, or gRPC Network Management Interface (gNMI) protocols and query data on paths that may have been denied by the NACM configuration. A successful exploit could allow the attacker to access data that should have been restricted according to the NACM configuration. Note: This vulnerability requires that the attacker obtain the credentials from a valid user with privileges lower than 15, and that NACM was configured to provide restricted read access for that user.Show less

A vulnerability in the CLI of Cisco Catalyst SD-WAN Manager, formerly Cisco SD-WAN vManage, could allow an authenticated, local attacker to overwrite arbitrary files on the local file system of an affected device. To exploit this vulnerability, the attacker must have valid read-only credentials with CLI access on the affected system. This vulnerability is due to improper access controls on files that are on the local file system. An attacker could exploit this vulnerability by running a series of crafted commands on the local file system of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the affected device and gain privileges of the root user. To exploit this vulnerability, an attacker would need to have CLI access as a low-privilege user.Show less

A vulnerability in the management API of Cisco Catalyst Center, formerly Cisco DNA Center, could allow an unauthenticated, remote attacker to read and modify the outgoing proxy configuration settings. This vulnerability is due to the lack of authentication in an API endpoint. An attacker could exploit this vulnerability by sending a request to the affected API of a Catalyst Center device. A successful exploit could allow the attacker to view or modify the outgoing proxy configuration, which could disrupt internet traffic from Cisco Catalyst Center or may allow the attacker to intercept outbound internet traffic.Show less

A vulnerability in Cisco IOS XE Wireless Controller Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of access point (AP) Cisco Discovery Protocol (CDP) neighbor reports when they are processed by the wireless controller. An attacker could exploit this vulnerability by sending a crafted CDP packet to an AP. A successful exploit could allow the attacker to cause an unexpected reload of the wireless controller that is managing the AP, resulting in a DoS condition that affects the wireless network.Show less

A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker with privilege level 15 to elevate privileges to root on the underlying operating system of an affected device. This vulnerability is due to insufficient input validation when processing specific configuration commands. An attacker could exploit this vulnerability by including crafted input in specific configuration commands. A successful exploit could allow the attacker to elevate privileges to root on the underlying operating system of an affected device. The security impact rating (SIR) of this advisory has been raised to High because an attacker could gain access to the underlying operating system of the affected device and perform potentially undetected actions. Note: The attacker must have privileges to enter configuration mode on the affected device. This is usually referred to as privilege level 15.Show less
