EMC Replication Manager (RM) is affected by a remote code execution vulnerability that may be exploited by an attacker to compromise an affected system. A remote unauthenticated attacker may execute arbitrary commands on an RM Client, with high privileges, by starting a rogue RM Server that connects to the RM Client and executes the malicious script/payload that is placed in an SMB share, by the attacker, that is accessible to the RM Client. Affected include EMC Replication Manager versions prior to 5.5.3 on all supported OS, EMC Network Module for Microsoft version 3.x, and EMC Networker Module for Microsoft version 8.2.x.
