A vulnerability in the configuration archive functionality of Cisco DNA Center could allow any privilege-level authenticated, remote attacker to obtain the full unmasked running configuration of managed devices. The vulnerability is due to the configuration archives files being stored in clear text, which can be retrieved by various API calls. An attacker could exploit this vulnerability by authenticating to the device and executing a series of API calls. A successful exploit could allow the attacker to retrieve the full unmasked running configurations of managed devices.

Weakness

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

Affected Software

Name Vendor Start Version End Version
Dna_center Cisco * 2.1.1.0 (excluding)

Extended Description

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
