Vulnerabilities > CVE-2023-20059 - Cleartext Storage of Sensitive Information vulnerability in Cisco DNA Center
Attack vector
NETWORK Attack complexity
LOW Privileges required
LOW Confidentiality impact
HIGH Integrity impact
NONE Availability impact
NONE Summary
A vulnerability in the implementation of the Cisco Network Plug-and-Play (PnP) agent of Cisco DNA Center could allow an authenticated, remote attacker to view sensitive information in clear text. The attacker must have valid low-privileged user credentials. This vulnerability is due to improper role-based access control (RBAC) with the integration of PnP. An attacker could exploit this vulnerability by authenticating to the device and sending a query to an internal API. A successful exploit could allow the attacker to view sensitive information in clear text, which could include configuration files.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Lifting Data Embedded in Client Distributions An attacker can resort to stealing data embedded in client distributions or client code in order to gain certain information. This information can reveal confidential contents, such as account numbers, or can be used as an intermediate step in a larger attack (such as by stealing keys/credentials).
