IBM Storwize V7000 Unified CIFS options incorrect permissions
|storwize-cifs-incorrect-permissions (80970)||Medium Risk|
IBM Storwize V7000 Unified could apply incorrect permissions to data, caused by an error in the SMB2 server configuration. Under certain conditions, a wrong set of CIFS options could be applied to V7000 Unified CIFS exports. This could allow a remote authenticated attacker to gain read-write access to data that was configured as read only.
