CVE-2018-9148
Western Digital WD My Cloud v04.05.00-320 devices embed the session token (aka PHPSESSID) in filenames, which makes it easier for attackers to bypass authentication by listing a directory.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
