Firmware update planned to fix CVE-2019-18929, CVE-2019-18930 and CVE-2019-18931 for EX2 Ultra?

November last year three vulnerabilities with the CVEs CVE-2019-18929, CVE-2019-18930 and CVE-2019-18931 with a severity of HIGH and a CVSS score ranging between 8.8 and 9.0 have been published in public for the EX2 Ultra firmware versions 2.31.183 and 2.31.195:

As there is no mention of a fix for these CVEs in the recent New Release - My Cloud Firmware Version 2.31.204 (12/16/2019) i would like to ask for any plans to fix these in one of the next firmware versions?


I would like to know that too.

It has been 4 months since publication of those vulnerabilities.

Thank you very much for this reply.

It seems the description.txt available in the linked github repositories of the Researcher contains the following text so your PSIRT might be already aware / informed about this:

[Has vendor confirmed or acknowledged the vulnerability?]


Vendor Confirmed, Local/Root PoC for NFS .

(Too) many months later. Still no update to resolve these high risk vulnerabilities?

Thank you! Both My Cloud ex2 ultra systems say that they cannot connect to update service (it worked flawless in the past, and I introduced no significant changes in my network devices or settings). And I could not find this new version with Google.
Kind regards, Maurice.

My DL NAS has, today, collected the security update from WD’s firmware servers and is set to install the update while I sleep.

I guess it’s a good thing I keep the option to disallow Dashboard access from any IP address.
Still, I also do wonder why it has taken so long.
