Vulnerability Details
This vulnerability allows remote attackers to disclose sensitive information
on vulnerable installations of EMC Appsync. Although authentication is
required to exploit this vulnerability, the existing authentication mechanism
can be easily bypassed.
The specific flaw exists within Apollo REST services, which listens on TCP
port 8445 by default. When parsing the query request parameter, the process
does not properly validate a user-supplied string before using it to construct
SQL queries. An attacker can leverage this vulnerability to disclose sensitive
information under the context of SYSTEM.
Vendor Response
EMC has issued an update to correct this vulnerability. More details can be
