A vulnerability in the TCL scripting subsystem of Cisco NX-OS System Software could allow an authenticated, local attacker to escape the interactive TCL shell and gain unauthorized access to the underlying operating system of the device. The vulnerability exists due to insufficient input validation of user-supplied files passed to the interactive TCL shell of the affected device. An attacker could exploit this vulnerability to escape the scripting sandbox and execute arbitrary commands on the underlying operating system with the privileges of the authenticated user. To exploit this vulnerability, an attacker must have local access and be authenticated to the targeted device with administrative or tclsh execution privileges. This vulnerability affects the following products running Cisco NX-OS System Software: Multilayer Director Switches, Nexus 2000 Series Fabric Extenders, Nexus 3000 Series Switches, Nexus 3500 Platform Switches, Nexus 5000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Nexus 9000 Series Switches in standalone NX-OS mode, Nexus 9500 R-Series Line Cards and Fabric Modules, Unified Computing System Manager. • http://www.securityfocus.com/bid/102168 http://www.securitytracker.com/id/1039936 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171129-nxos5 • CWE-20: Improper Input Validation •

A vulnerability in the CLI of Cisco NX-OS System Software could allow an authenticated, local attacker to perform a command injection attack. An attacker would need valid administrator credentials to perform this exploit. The vulnerability is due to insufficient input validation during the installation of a software patch. An attacker could exploit this vulnerability by installing a crafted patch image with the vulnerable operation occurring prior to patch activation. An exploit could allow the attacker to execute arbitrary commands on an affected system as root. • http://www.securitytracker.com/id/1039939 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171129-nxos8 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •

A vulnerability in the Open Agent Container (OAC) feature of Cisco Nexus Series Switches could allow an unauthenticated, local attacker to read and send packets outside the scope of the OAC. The vulnerability is due to insufficient internal security measures in the OAC feature. An attacker could exploit this vulnerability by crafting specific packets for communication on the device-internal network. A successful exploit could allow the attacker to run code on the underlying host operating system. OAC is not enabled by default. • http://www.securityfocus.com/bid/102027 http://www.securitytracker.com/id/1039940 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171129-nxos9 • CWE-264: Permissions, Privileges, and Access Controls CWE-668: Exposure of Resource to Wrong Sphere •

A vulnerability in Cisco NX-OS System Software patch installation could allow an authenticated, local attacker to write a file to arbitrary locations. The vulnerability is due to insufficient restrictions in the patch installation process. An attacker could exploit this vulnerability by installing a crafted patch image on an affected device. The vulnerable operation occurs prior to patch activation. An exploit could allow the attacker to write arbitrary files on an affected system as root. • http://www.securityfocus.com/bid/102160 http://www.securitytracker.com/id/1039931 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171129-nxos1 • CWE-434: Unrestricted Upload of File with Dangerous Type •

https://notcve.org/view.php?id=CVE-2017-12338
A vulnerability in the CLI of Cisco NX-OS System Software could allow an authenticated, local attacker to read the contents of arbitrary files. The vulnerability is due to insufficient input validation for a specific CLI command. An attacker could exploit this vulnerability by issuing a crafted command on the CLI. An exploit could allow the attacker unauthorized access to read arbitrary files on the underlying local file system. On products that support multiple virtual device contexts (VDCs), this vulnerability could allow an attacker to read files from any VDC. • http://www.securitytracker.com/id/1039937 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171129-nxos6 • CWE-20: Improper Input Validation •
