Advisory ID: NTAP-20190627-0001 Version: 3.0 Last updated: 08/14/2019 Status: Final. CVEs: CVE-2019-5497
Summary
NetApp AFF A700s Baseboard Management Controller (BMC) firmware versions 1.22 and higher were shipped with a default account enabled that could allow unauthorized arbitrary command execution.
Impact
Exploitation of this vulnerability can result in unauthorized arbitrary command execution.
This only affects the BMC of an AFF A700s storage system. The Service Processors (SP) or BMCs used on other storage system models are not affected by this specific vulnerability.
The vulnerability is addressed by applying patched BMC firmware to the BMC of the AFF A700s system. An ONTAP update is not required.
While the BMC firmware update requires a reboot of the BMC, the process is nondisruptive to ONTAP.
Certain versions of clustered Data ONTAP included affected versions of the AFF A700s BMC firmware. ONTAP P-releases that include the patched AFF A700s BMC firmware will be available for all versions under Full Support except 9.1 which needs to be updated using the BMC patch. Continue to monitor the advisory for updates.
