CVSS: 9.8EPSS: 0%CPEs: 50EXPL: 0CVE-2021-1361 – Cisco NX-OS Software Unauthenticated Arbitrary File Actions Vulnerability
https://notcve.org/view.php?id=CVE-2021-1361
A vulnerability in the implementation of an internal file management service for Cisco Nexus 3000 Series Switches and Cisco Nexus 9000 Series Switches in standalone NX-OS mode that are running Cisco NX-OS Software could allow an unauthenticated, remote attacker to create, delete, or overwrite arbitrary files with root privileges on the device. This vulnerability exists because TCP port 9075 is incorrectly configured to listen and respond to external connection requests. An attacker could exploit this vulnerability by sending crafted TCP packets to an IP address that is configured on a local interface on TCP port 9075. A successful exploit could allow the attacker to create, delete, or overwrite arbitrary files, including sensitive files that are related to the device configuration. For example, the attacker could add a user account without the device administrator knowing. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-3000-9000-fileaction-QtLzDRy2 • CWE-552: Files or Directories Accessible to External Parties •
CVSS: 6.5EPSS: 0%CPEs: 14EXPL: 0CVE-2021-1389 – Cisco IOS XR and Cisco NX-OS Software IPv6 Access Control List Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1389
A vulnerability in the IPv6 traffic processing of Cisco IOS XR Software and Cisco NX-OS Software for certain Cisco devices could allow an unauthenticated, remote attacker to bypass an IPv6 access control list (ACL) that is configured for an interface of an affected device. The vulnerability is due to improper processing of IPv6 traffic that is sent through an affected device. An attacker could exploit this vulnerability by sending crafted IPv6 packets that traverse the affected device. A successful exploit could allow the attacker to access resources that would typically be protected by the interface ACL. Una vulnerabilidad en el procesamiento del tráfico IPv6 del Software Cisco IOS XR, y el Software Cisco NX-OS para determinados dispositivos Cisco, podría permitir a un atacante remoto no autenticado omitir una lista de control de acceso (ACL) IPv6 configurada para una interfaz de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipv6-acl-CHgdYk8j • CWE-284: Improper Access Control •
CVSS: 6.9EPSS: 0%CPEs: 18EXPL: 0CVE-2019-1732 – Cisco NX-OS Software Remote Package Manager Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1732
A vulnerability in the Remote Package Manager (RPM) subsystem of Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to leverage a time-of-check, time-of-use (TOCTOU) race condition to corrupt local variables, which could lead to arbitrary command injection. The vulnerability is due to the lack of a proper locking mechanism on critical variables that need to stay static until used. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a set of RPM-related CLI commands. A successful exploit could allow the attacker to perform arbitrary command injection. The attacker would need administrator credentials for the targeted device. • http://www.securityfocus.com/bid/108361 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-rpm-injec • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-667: Improper Locking •

https://notcve.org/view.php?id=CVE-2019-1733
A vulnerability in the NX API (NX-API) Sandbox interface for Cisco NX-OS Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the NX-API Sandbox interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the NX-API Sandbox interface. An attacker could exploit this vulnerability by persuading a user of the NX-API Sandbox interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected NX-API Sandbox interface. Una vulnerabilidad en la NX API (NX-API) Sandbox para el programa NX-OS de Cisco podría permitir a un atacante remoto autorizado realizar un ataque de tipo cross-site scripting (XSS) contra un usuario de la NX-API en la interfaz Sandbox de un dispositivo afectado. • http://www.securityfocus.com/bid/108348 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-nxapi-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 7.2EPSS: 0%CPEs: 33EXPL: 0CVE-2019-1727 – Cisco NX-OS Software Python Parser Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1727
A vulnerability in the Python scripting subsystem of Cisco NX-OS Software could allow an authenticated, local attacker to escape the Python parser and issue arbitrary commands to elevate the attacker's privilege level. The vulnerability is due to insufficient sanitization of user-supplied parameters that are passed to certain Python functions in the scripting sandbox of the affected device. An attacker could exploit this vulnerability to escape the scripting sandbox and execute arbitrary commands to elevate the attacker's privilege level. To exploit this vulnerability, the attacker must have local access and be authenticated to the targeted device with administrative or Python execution privileges. These requirements could limit the possibility of a successful exploit. • http://www.securityfocus.com/bid/108341 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-pyth-escal • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-264: Permissions, Privileges, and Access Controls •
