A vulnerability allows attackers to execute arbitrary code on vulnerable installations of EMC RepliStor Server. User interaction is not required to exploit this vulnerability. The specific flaw exists in the RepliStor Server Service that listens by default on TCP port 7144. The vulnerable function trusts a user-supplied size value allowing an attacker to create an undersized buffer. A later call to recv() overflows that buffer allowing for arbitrary code execution in the context of the SYSTEM user. Replistor version 6.1.3 is affected.
