A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker with level-15 privileges or an unauthenticated attacker with physical access to an affected device to execute persistent code at boot time and break the chain of trust. This vulnerability is due to improper validation of software packages. An attacker could exploit this vulnerability by placing a crafted file into a specific location on an affected device. A successful exploit could allow the attacker to execute persistent code on the underlying operating system. Because this vulnerability allows an attacker to bypass a major security feature of a device, Cisco has raised the Security Impact Rating (SIR) of this advisory from Medium to High.
CVE-2025-20340 1 Cisco 1 Ios Xr Software 2026-04-15 7.4 High
A vulnerability in the Address Resolution Protocol (ARP) implementation of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to trigger a broadcast storm, leading to a denial of service (DoS) condition on an affected device.  This vulnerability is due to how Cisco IOS XR Software processes a high, sustained rate of ARP traffic hitting the management interface. Under certain conditions, an attacker could exploit this vulnerability by sending an excessive amount of traffic to the management interface of an affected device, overwhelming its ARP processing capabilities. A successful exploit could result in degraded device performance, loss of management connectivity, and complete unresponsiveness of the system, leading to a DoS condition.

An attacker could exploit this vulnerability by connecting to the debug port and executing debug commands. A successful exploit could allow the attacker to view sensitive debugging information.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
CVE-2019-1815 1 Cisco 1 Meraki Mx Firmware 2026-04-15 N/A
A security vulnerability was discovered in the local status page functionality of Cisco Meraki’s MX67 and MX68 security appliance models that may allow unauthenticated individuals to access and download logs containing sensitive, privileged device information. The vulnerability is due to improper access control to the files holding debugging and maintenance information, and is only exploitable when the local status page is enabled on the device. An attacker exploiting this vulnerability may obtain access to wireless pre-shared keys, Site-to-Site VPN key and other sensitive information. Under certain circumstances, this information may allow an attacker to obtain administrative-level access to the device.
CVE-2025-20160 1 Cisco 2 Ios, Ios Xe Software 2026-04-15 8.1 High
A vulnerability in the implementation of the TACACS+ protocol in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to view sensitive data or bypass authentication. This vulnerability exists because the system does not properly check whether the required TACACS+ shared secret is configured. A machine-in-the-middle attacker could exploit this vulnerability by intercepting and reading unencrypted TACACS+ messages or impersonating the TACACS+ server and falsely accepting arbitrary authentication requests. A successful exploit could allow the attacker to view sensitive information in a TACACS+ message or bypass authentication and gain access to the affected device.
CVE-2025-20164 1 Cisco 1 Ios 2026-04-15 8.3 High
A vulnerability in the Cisco Industrial Ethernet Switch Device Manager (DM) of Cisco IOS Software could allow an authenticated, remote attacker to elevate privileges.
