The remote host is vulnerable to a buffer overflow.
The remote host is running EMC Legato Networker, an enterprise application that enables centralized file management, backup and more. This version of Legato is vulnerable to a flaw in the 'nsrexecd.exe' application. An attacker exploiting this flaw would only require the ability to connect to the nsrexecd.exe listening port (111/TCP). Successful exploitation would result in the execution of arbitrary code.
Upgrade or patch according to vendor recommendations.
