The vendor published a different MD5 for this file. It was kept because two separate downloads were identical, and it passed the integrity check; vendors occasionally publish wrong checksums.

About the security baseline: firmware with a higher security baseline can stop a device going back to older firmware. A device already on a higher baseline than V2.3 may refuse this file, and after installing it you may not be able to downgrade to firmware with a lower baseline.
