A vulnerability was found in Cisco Data Center Network Manager (affected version unknown). It has been classified as problematic. This affects an unknown functionality of the component SOAP API. The manipulation as part of a API Request leads to a xml external entity reference vulnerability. CWE is classifying the issue as CWE-611. The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. This is going to have an impact on confidentiality. The summary by CVE is:

A vulnerability in the SOAP API of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker to gain read access to information that is stored on an affected system. To exploit this vulnerability, an attacker would need administrative privileges on the DCNM application. The vulnerability exists because the SOAP API improperly handles XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by inserting malicious XML content in an API request. A successful exploit could allow the attacker to read arbitrary files from the affected device. Note: The severity of this vulnerability is aggravated by the vulnerabilities described in the Cisco Data Center Network Manager Authentication Bypass Vulnerabilities advisory, published simultaneously with this one.

The weakness was disclosed 01/06/2020 as cisco-sa-20200102-dcnm-xml-ext as confirmed advisory (Website). The advisory is shared at tools.cisco.com. This vulnerability is uniquely identified as CVE-2019-15983 since 09/06/2019. It is possible to initiate the attack remotely. The successful exploitation needs a authentication. Neither technical details nor an exploit are publicly available.

Upgrading eliminates this vulnerability.

The entries VDB-148320, VDB-148319, VDB-148318 and VDB-148316 are pretty similar.
