CVSS: 5.3EPSS: 0%CPEs: 152EXPL: 0CVE-2024-20284 – Cisco NX-OS Software Python Parser Escape Vulnerability
https://notcve.org/view.php?id=CVE-2024-20284
A vulnerability in the Python interpreter of Cisco NX-OS Software could allow an authenticated, low-privileged, local attacker to escape the Python sandbox and gain unauthorized access to the underlying operating system of the device. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by manipulating specific functions within the Python interpreter. A successful exploit could allow an attacker to escape the Python sandbox and execute arbitrary commands on the underlying operating system with the privileges of the authenticated user. Note: An attacker must be authenticated with Python execution privileges to exploit these vulnerabilities. For more information regarding Python execution privileges, see product-specific documentation, such as the section of the Cisco Nexus 9000 Series NX-OS Programmability Guide. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-psbe-ce-YvbTn5du https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/105x/programmability/cisco-nexus-9000-series-nx-os-programmability-guide-105x/m-n9k-python-api-101x.html?bookSearch=true#concept_A2CFF094ADCB414C983EA06AD8E9A410 • CWE-693: Protection Mechanism Failure •

https://notcve.org/view.php?id=CVE-2024-20399
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands as root on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of arguments that are passed to specific configuration CLI commands. An attacker could exploit this vulnerability by including crafted input as the argument of an affected configuration CLI command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with the privileges of root. Note: To successfully exploit this vulnerability on a Cisco NX-OS device, an attacker must have Administrator credentials. Una vulnerabilidad en la CLI del software Cisco NX-OS podría permitir que un atacante local autenticado ejecute comandos arbitrarios como root en el sistema operativo subyacente de un dispositivo afectado. Esta vulnerabilidad se debe a una validación insuficiente de los argumentos que se pasan a comandos CLI de configuración específicos. • https://github.com/Blootus/CVE-2024-20399-Cisco-RCE https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-cmd-injection-xD9OhyOP https://www.sygnia.co/threat-reports-and-advisories/china-nexus-threat-group-velvet-ant-exploits-cisco-0-day • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 6.6EPSS: 0%CPEs: 481EXPL: 0CVE-2024-20294
https://notcve.org/view.php?id=CVE-2024-20294
A vulnerability in the Link Layer Discovery Protocol (LLDP) feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of specific fields in an LLDP frame. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface of an affected device and having an authenticated user retrieve LLDP statistics from the affected device through CLI show commands or Simple Network Management Protocol (SNMP) requests. A successful exploit could allow the attacker to cause the LLDP service to crash and stop running on the affected device. In certain situations, the LLDP crash may result in a reload of the affected device. Note: LLDP is a Layer 2 link protocol. To exploit this vulnerability, an attacker would need to be directly connected to an interface of an affected device, either physically or logically (for example, through a Layer 2 Tunnel configured to transport the LLDP protocol). • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-lldp-dos-z7PncTgt • CWE-805: Buffer Access with Incorrect Length Value •
