CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2019-1591 – Cisco Nexus 9000 Series Fabric Switches Application Centric Infrastructure Mode Shell Escape Vulnerability
https://notcve.org/view.php?id=CVE-2019-1591
A vulnerability in a specific CLI command implementation of Cisco Nexus 9000 Series ACI Mode Switch Software could allow an authenticated, local attacker to escape a restricted shell on an affected device. The vulnerability is due to insufficient sanitization of user-supplied input when issuing a specific CLI command with parameters on an affected device. An attacker could exploit this vulnerability by authenticating to the device CLI and issuing certain commands. A successful exploit could allow the attacker to escape the restricted shell and execute arbitrary commands with root-level privileges on the affected device. This vulnerability only affects Cisco Nexus 9000 Series ACI Mode Switches that are running a release prior to 14.0(3d). • http://www.securityfocus.com/bid/107311 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-aci-shell-escape • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.8EPSS: 0%CPEs: 20EXPL: 0CVE-2019-1593 – Cisco NX-OS Software Bash Shell Role-Based Access Control Bypass Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1593
A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to escalate their privilege level by executing commands authorized to other user roles. The attacker must authenticate with valid user credentials. The vulnerability is due to the incorrect implementation of a Bash shell command that allows role-based access control (RBAC) to be bypassed. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Bash prompt. A successful exploit could allow the attacker to escalate their privilege level by executing commands that should be restricted to other roles. • http://www.securityfocus.com/bid/107324 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nx-os-bash-escal • CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2019-1588
A vulnerability in the Cisco Nexus 9000 Series Fabric Switches running in Application-Centric Infrastructure (ACI) mode could allow an authenticated, local attacker to read arbitrary files on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms of user-supplied input sent to an affected device. A successful exploit could allow the attacker unauthorized access to read arbitrary files on an affected device. This vulnerability has been fixed in version 14.0(1h). Una vulnerabilidad en Cisco Nexus 9000 Series Fabric Switches que se ejecuta en el modo Application-Centric Infrastructure (ACI) podría permitir a un atacante local autenticado leer archivos arbitrarios en un dispositivo afectado. • http://www.securityfocus.com/bid/107316 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-aci-file-read • CWE-20: Improper Input Validation CWE-269: Improper Privilege Management •
CVSS: 8.8EPSS: 0%CPEs: 17EXPL: 0CVE-2018-0395 – Cisco FXOS and NX-OS Software Link Layer Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0395
A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when the device unexpectedly reloads. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface on the targeted device. A successful exploit could allow the attacker to cause the switch to reload unexpectedly. Una vulnerabilidad en la implementación LLDP (Link Layer Discovery Protocol) para Cisco FXOS Software y Cisco NX-OS Software podría permitir que un atacante adyacente no autenticado cree una condición de denegación de servicio (DoS) cuando el dispositivo se recarga inesperadamente. • http://www.securityfocus.com/bid/105674 http://www.securitytracker.com/id/1041919 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181017-fxnx-os-dos • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2017-6770
Cisco IOS 12.0 through 15.6, Adaptive Security Appliance (ASA) Software 7.0.1 through 9.7.1.2, NX-OS 4.0 through 12.0, and IOS XE 3.6 through 3.18 are affected by a vulnerability involving the Open Shortest Path First (OSPF) Routing Protocol Link State Advertisement (LSA) database. This vulnerability could allow an unauthenticated, remote attacker to take full control of the OSPF Autonomous System (AS) domain routing table, allowing the attacker to intercept or black-hole traffic. The attacker could exploit this vulnerability by injecting crafted OSPF packets. Successful exploitation could cause the targeted router to flush its routing table and propagate the crafted OSPF LSA type 1 update throughout the OSPF AS domain. To exploit this vulnerability, an attacker must accurately determine certain parameters within the LSA database on the target router. • http://www.securityfocus.com/bid/100005 http://www.securitytracker.com/id/1039005 http://www.securitytracker.com/id/1039006 http://www.securitytracker.com/id/1039007 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170727-ospf • CWE-20: Improper Input Validation •
