To exploit this vulnerability, an attacker would need administrative privileges on the DCNM application.\r\n\r\nThe 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.\r\n\r\n\r\nNote: The severity of this vulnerability is aggravated by the vulnerabilities described in the Cisco Data Center Network Manager Authentication Bypass Vulnerabilities [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200102-dcnm-auth-bypass\"] advisory, published simultaneously with this one.\r\n\r\nCisco has released software updates that address this vulnerability.
