CVSS: 8.8EPSS: 0%CPEs: 76EXPL: 0CVE-2024-20398 – Cisco IOS XR Software Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2024-20398
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. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-priv-esc-CrG5vhCq • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
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 •
CVSS: 5.5EPSS: 0%CPEs: 66EXPL: 0CVE-2024-20343 – Cisco IOS XR Software CLI Arbitrary File Read Vulnerability
https://notcve.org/view.php?id=CVE-2024-20343
A vulnerability in the CLI of Cisco IOS XR Software could allow an authenticated, local attacker to read any file in the file system of the underlying Linux operating system. The attacker must have valid credentials on the affected device. This vulnerability is due to incorrect validation of the arguments that are passed to a specific CLI command. An attacker could exploit this vulnerability by logging in to an affected device with low-privileged credentials and using the affected command. A successful exploit could allow the attacker access files in read-only mode on the Linux file system. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-shellutil-HCb278wD • CWE-284: Improper Access Control •

https://notcve.org/view.php?id=CVE-2024-20319
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 •
CVSS: 6.5EPSS: 0%CPEs: 82EXPL: 0CVE-2024-20262
https://notcve.org/view.php?id=CVE-2024-20262
A vulnerability in the Secure Copy Protocol (SCP) and SFTP feature of Cisco IOS XR Software could allow an authenticated, local attacker to create or overwrite files in a system directory, which could lead to a denial of service (DoS) condition. The attacker would require valid user credentials to perform this attack. This vulnerability is due to a lack of proper validation of SCP and SFTP CLI input parameters. An attacker could exploit this vulnerability by authenticating to the device and issuing SCP or SFTP CLI commands with specific parameters. A successful exploit could allow the attacker to impact the functionality of the device, which could lead to a DoS condition. The device may need to be manually rebooted to recover. Note: This vulnerability is exploitable only when a local user invokes SCP or SFTP commands at the Cisco IOS XR CLI. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-scp-dos-kb6sUUHw • CWE-269: Improper Privilege Management •
