Official Description

A vulnerability in the Cisco Nexus Dashboard Fabric Controller (NDFC) software, formerly Cisco Data Center Network Manager (DCNM), could allow an attacker with access to a backup file to view sensitive information.

This vulnerability is due to the improper storage of sensitive information within config only and full backup files. An attacker could exploit this vulnerability by parsing the contents of a backup file that is generated from an affected device. A successful exploit could allow the attacker to access sensitive information, including NDFC-connected device credentials, the NDFC site manager private key, and the scheduled backup file encryption key.

Technical Analysis

CVE-2024-20448 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 8.6.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
