A vulnerability in the background operations functionality of Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an authenticated, local attacker to gain elevated privileges as root on an affected device. The vulnerability is due to insufficient validation of user-supplied files on an affected device. An attacker could exploit this vulnerability by logging in to the CLI of the affected device and creating a crafted file in a specific directory on the filesystem. A successful exploit could allow the attacker to execute arbitrary operating system commands as root on an affected device.
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
