Who is Vulnerable?
Vulnerability Description	EMC RepliStor is a data recovery and protection system exclusively for Microsoft Windows. Recovery and protection are achieved by providing easy to use data replication to multiple sources in real-time or on a schedule. Files, directories, volumes and shares can be replicated as long as TCP/IP connectivity exists between the source and destination. A denial of service vulnerability exists in EMC RepliStor. The vulnerability is due to an input validation error while parsing a specially crafted packet sent to certain services. Remote unauthenticated attackers can exploit this vulnerability by sending a malicious packet to the services on ports 7144/TCP and 7145/TCP. Successful exploitation of this vulnerability would abnormally terminate the targeted service and cause a denial of service condition.
