2.2(8c)B

Description (partial)

Symptom:
While UCSM is supposed to accept only certain types of files viz. .BIN or .GBIN. While UCSM restricts from uploading any scripts or .tar or.zip files, there is no restriction for uploading .ISO images which can cause space utilization issues in the bootflash. Need to restrict the kind of files which can be uploaded to the UCSM.

We tend to see driver ISO files in the /bootflash/received folder once we start the driver iSO file upload deliberately although driver files are not expected on UCSM.

Conditions:
When we use the 'download firmware' feature of the UCSM getting into Equipment >> Equipment >> Firmware management >> download firmware, there is no clear restriction to the kind of image we upload.
