CVE-2024-20449: NDFC Path Traversal via SCP Enables RootExec
CVE-2024-20449 Published on October 2, 2024

A vulnerability in Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an authenticated, remote attacker with low privileges to execute arbitrary code on an affected device. This vulnerability is due to improper path validation. An attacker could exploit this vulnerability by using the Secure Copy Protocol (SCP) to upload malicious code to an affected device using path traversal techniques. A successful exploit could allow the attacker to execute arbitrary code in a specific container with the privileges of root.

Weakness Type

Relative Path Traversal

The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory.
