CVE-2024-20266 | 1 Cisco | 1 Ios Xr Software | 2025-07-12 | 5.3 Medium |
A vulnerability in the DHCP version 4 (DHCPv4) server feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to trigger a crash of the dhcpd process, resulting in a denial of service (DoS) condition. This vulnerability exists because certain DHCPv4 messages are improperly validated when they are processed by an affected device. An attacker could exploit this vulnerability by sending a malformed DHCPv4 message to an affected device. A successful exploit could allow the attacker to cause a crash of the dhcpd process. While the dhcpd process is restarting, which may take approximately two minutes, DHCPv4 server services are unavailable on the affected device. This could temporarily prevent network access to clients that join the network during that time period and rely on the DHCPv4 server of the affected device. Notes: Only the dhcpd process crashes and eventually restarts automatically. The router does not reload. This vulnerability only applies to DHCPv4. DHCP version 6 (DHCPv6) is not affected. | ||||
CVE-2024-20315 | 1 Cisco | 1 Ios Xr Software | 2025-04-15 | 5.8 Medium |
A vulnerability in the access control list (ACL) processing on MPLS interfaces in the ingress direction of Cisco IOS XR Software could allow an unauthenticated, remote attacker to bypass a configured ACL. This vulnerability is due to improper assignment of lookup keys to internal interface contexts. An attacker could exploit this vulnerability by attempting to send traffic through an affected device. A successful exploit could allow the attacker to access resources behind the affected device that were supposed to be protected by a configured ACL. | ||||
CVE-2015-0769 | 1 Cisco | 1 Ios Xr Software | 2025-04-12 | N/A |
Cisco IOS XR 4.0.1 through 4.2.0 for CRS-3 Carrier Routing System allows remote attackers to cause a denial of service (NPU ASIC scan and line-card reload) via crafted IPv6 extension headers, aka Bug ID CSCtx03546. | ||||
CVE-2023-20236 | 1 Cisco | 53 8201, 8202, 8208 and 50 more | 2024-11-21 | 6.7 Medium |
A vulnerability in the iPXE boot function of Cisco IOS XR software could allow an authenticated, local attacker to install an unverified software image on an affected device. This vulnerability is due to insufficient image verification. An attacker could exploit this vulnerability by manipulating the boot parameters for image verification during the iPXE boot process on an affected device. A successful exploit could allow the attacker to boot an unverified software image on the affected device. | ||||
CVE-2022-20655 | 1 Cisco | 8 Carrier Packet Transport, Catalyst Sd-wan Manager, Enterprise Nfv Infrastructure Software and 5 more | 2024-11-18 | 8.8 High |
A vulnerability in the implementation of the CLI on a device that is running ConfD could allow an authenticated, local attacker to perform a command injection attack. The vulnerability is due to insufficient validation of a process argument on an affected device. An attacker could exploit this vulnerability by injecting commands during the execution of this process. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with the privilege level of ConfD, which is commonly root. | ||||
CVE-2024-20390 | 1 Cisco | 2 Ios Xr, Ios Xr Software | 2024-10-07 | 5.3 Medium |
A vulnerability in the Dedicated XML Agent feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) on XML TCP listen port 38751. This vulnerability is due to a lack of proper error validation of ingress XML packets. An attacker could exploit this vulnerability by sending a sustained, crafted stream of XML traffic to a targeted device. A successful exploit could allow the attacker to cause XML TCP port 38751 to become unreachable while the attack traffic persists. | ||||
CVE-2024-20398 | 1 Cisco | 2 Ios Xr, Ios Xr Software | 2024-10-03 | 8.8 High |
A vulnerability in the CLI of Cisco IOS XR Software could allow an authenticated, local attacker to obtain read/write file system access on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of user arguments that are passed to specific CLI commands. An attacker with a low-privileged account could exploit this vulnerability by using crafted commands at the prompt. A successful exploit could allow the attacker to elevate privileges to root. |
