VULNERABILITY DETAILS

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Cisco Data Center Network Manager. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

The specific flaw exists within the processing of requests to the fm/fmrest/virtualportchannel/domain endpoint. When parsing the filterStr parameter, the process does not properly validate a user-supplied string before using it to construct SQL queries. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM.
