Description
A vulnerability in the backup restore functionality of Cisco Nexus Dashboard could allow an authenticated, remote attacker to conduct a path traversal attack on an affected device. This vulnerability is due to insufficient validation of the contents of a backup file. An attacker with valid Administrator credentials could exploit this vulnerability by restoring a crafted backup file to an affected device. A successful exploit could allow the attacker to gain root privileges on the underlying shell on the affected device.

Mitigation Strategies

To mitigate this vulnerability, immediately upgrade your Cisco Nexus Dashboard to the fixed software release 4.1(1g) or later. Verify hardware and software compatibility before upgrading. Since no workarounds are available, upgrading is the primary mitigation step. If needed, consult Cisco TAC or maintenance providers for assistance. [1]

Executive Summary

This vulnerability is a path traversal flaw in the backup restore functionality of Cisco Nexus Dashboard. It occurs because the system does not properly validate the contents of a backup file. An attacker who has valid Administrator credentials can exploit this by restoring a specially crafted backup file, which allows them to perform a path traversal attack and gain root privileges on the underlying shell of the affected device. [1]

Impact Analysis

If exploited, this vulnerability could allow an attacker with Administrator credentials to gain root-level access to the affected device. This means the attacker could fully control the device's underlying operating system shell, potentially leading to unauthorized access, data compromise, and manipulation of the device's functions.
