The nsrpush process in the client in EMC NetWorker before 7.6.5.3 and 8.x before 8.0.1.4 sets weak permissions for unspecified files, which allows local users to gain privileges via unknown vectors.

librpc.dll in nsrexecd in EMC NetWorker before 7.5 SP4, 7.5.3.x before 7.5.3.5, and 7.6.x before 7.6.1.2 does not properly mitigate the possibility of a spoofed localhost source IP address, which allows remote attackers to (1) register or (2) unregister RPC services, and consequently cause a denial of service or obtain sensitive information from interprocess communication, via crafted UDP packets containing service commands.

Stack-based buffer overflow in the NetWorker Remote Exec Service (nsrexecd.exe) in EMC Software NetWorker 7.x.x allows remote attackers to execute arbitrary code via a (1) poll or (2) kill request with a "long invalid subcmd."

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

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.

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.
