EMC Legato NetWorker, Sun Solstice Backup 6.0 and 6.1, and StorEdge Enterprise Backup 7.0 through 7.2 rely on AUTHUNIX authentication, which relies on user ID for authentication and allows remote attackers to bypass authentication and gain privileges by spoofing a username or UID.

EMC Legato NetWorker, Solstice Backup 6.0 and 6.1, and StorEdge Enterprise Backup 6.0 through 7.2 do not properly verify authentication tokens, which allows remote attackers to gain privileges by modifying an authentication token.

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 pmapset and pmapunset commands, which allows remote attackers to (1) cause a denial of service by using pmapunset to un-register a NetWorker service, or (2) obtain sensitive information from NetWorker services by using pmapset to register a new service.
