The Legato PortMapper in EMC Legato NetWorker, Sun Solstice Backup 6.0 and 6.1, and StorEdge Enterprise Backup 7.0 through 7.2 does not restrict access to the pmap_set and pmap_unset commands, which allows remote attackers to (1) cause a denial of service by using pmap_unset to un-register a NetWorker service, or (2) obtain sensitive information from NetWorker services by using pmap_set to register a new service.
