Detailsinfo

A vulnerability, which was classified as critical, was found in Cisco DNA Center up to 1.2.4. This affects an unknown part of the component Software Image Management. The manipulation as part of a HTTP Requests leads to a input validation vulnerability. CWE is classifying the issue as CWE-441. 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.
