CVE-2024-20449: NDFC Path Traversal via SCP Enables RootExec
CVE-2024-20449 Published on October 2, 2024
Cisco Nexus Dashboard Fabric Controller Remote Code Execution Vulnerability
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.
Vulnerability Analysis
CVE-2024-20449 can be exploited with network access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to be very high.
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.
