Description

A vulnerability in the Software Image Management feature of Cisco DNA Center could allow an authenticated, remote attacker to access to internal services without additional authentication. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending arbitrary HTTP requests to internal services. An exploit could allow the attacker to bypass any firewall or other protections to access unauthorized internal services. DNAC versions prior to 1.2.5 are affected.

• CWE-441Unintended Proxy or Intermediary ('Confused Deputy')The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor.
• CWE-20Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
