CVSS: 8.8EPSS: 0%CPEs: 271EXPL: 0CVE-2024-20381 – Cisco Network Services Orchestrator Configuration Update Authorization Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2024-20381
A vulnerability in the JSON-RPC API feature in ConfD that is used by the web-based management interfaces of Cisco Crosswork Network Services Orchestrator (NSO), Cisco Optical Site Manager, and Cisco RV340 Dual WAN Gigabit VPN Routers could allow an authenticated, remote attacker to modify the configuration of an affected application or device. This vulnerability is due to improper authorization checks on the API. An attacker with privileges sufficient to access the affected application or device could exploit this vulnerability by sending malicious requests to the JSON-RPC API. A successful exploit could allow the attacker to make unauthorized modifications to the configuration of the affected application or device, including creating new user accounts or elevating their own privileges on an affected system.

CVSS: 5.3EPSS: 0%CPEs: 86EXPL: 0CVE-2024-20390 – Cisco IOS XR Software Dedicated XML Agent TCP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2024-20390
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. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-xml-tcpdos-ZEXvrU2S • CWE-940: Improper Verification of Source of a Communication Channel •

A vulnerability in the UDP forwarding code of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to bypass configured management plane protection policies and access the Simple Network Management Plane (SNMP) server of an affected device. This vulnerability is due to incorrect UDP forwarding programming when using SNMP with management plane protection. An attacker could exploit this vulnerability by attempting to perform an SNMP operation using broadcast as the destination address that could be processed by an affected device that is configured with an SNMP server. A successful exploit could allow the attacker to communicate to the device on the configured SNMP ports. Although an unauthenticated attacker could send UDP datagrams to the configured SNMP port, only an authenticated user can retrieve or modify data using SNMP requests. Una vulnerabilidad en el código de reenvío UDP del software Cisco IOS XR podría permitir que un atacante adyacente no autenticado omita las políticas de protección del plano de administración configuradas y acceda al servidor del Plano simple de administración de red (SNMP) de un dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snmp-uhv6ZDeF • CWE-284: Improper Access Control •

https://notcve.org/view.php?id=CVE-2024-20318
A vulnerability in the Layer 2 Ethernet services of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause the line card network processor to reset, resulting in a denial of service (DoS) condition. This vulnerability is due to the incorrect handling of specific Ethernet frames that are received on line cards that have the Layer 2 services feature enabled. An attacker could exploit this vulnerability by sending specific Ethernet frames through an affected device. A successful exploit could allow the attacker to cause the ingress interface network processor to reset, resulting in a loss of traffic over the interfaces that are supported by the network processor. Multiple resets of the network processor would cause the line card to reset, resulting in a DoS condition. Una vulnerabilidad en los servicios Ethernet de capa 2 del software Cisco IOS XR podría permitir que un atacante adyacente no autenticado provoque que el procesador de red de la tarjeta de línea se reinicie, lo que resultaría en una condición de denegación de servicio (DoS). • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xrl2vpn-jesrU3fc • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2024-20266
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. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-dhcp-dos-3tgPKRdm • CWE-476: NULL Pointer Dereference •
