As Synology explains in security advisories published two days after the flaws were demoed at Pwn2Own Ireland 2024 to hijack a Synology BeeStation BST150-4T device, the security flaws enable remote attackers to gain remote code execution as root on vulnerable NAS appliances exposed online.
“The vulnerability was initially discovered, within just a few hours, as a replacement for another Pwn2Own submission. The issue was disclosed to Synology immediately after demonstration, and within 48 hours a patch was made available which resolves the vulnerability,” Midnight Blue said.
From a different source:
Synology proactively sponsors and works with security researchers as part of product security initiatives. At this year’s Pwn2Own Ireland 2024 event, which took place in late October, we successfully discovered and resolved multiple security vulnerabilities.
While these vulnerabilities are not being exploited, we recommend all Synology device administrators immediately take action to secure their systems by updating due to the scope and severity of specific issues.
FYI, in case anyone is running 7.2.1, just be aware that you have to MANUALLY update because you need to agree to new terms that removes local hardware processing of some media types.

7.2.2-72806 Update 1 is the update with the new patches.
If you’re running Plex locally (i.e. - not in docker) you’ll need to manually install the updated 7.2.2 patch. You need to download it locally, then push it back up to your NAS bypassing the normal process. You can’t use the plex client to prompt the update, and you can’t use the synology package manager to update.
The package links on Reddit and some other sites are older versions that may not install

This was one of the rare times I installed a firmware update without waiting. They even sent an email telling me how urgent it was to get my NAS patched.
I definitely did not get that email. WTH?
If you are using any Synology products with your setup, you should go ahead and apply the recommended updates
Ugh but it’s acting as the SAN so I have to shut down like all my servers to run updates on it. What a PITA.
And this was how I learned that Video Station is no longer supported by Synology. If you want the updates, you’ll have to uninstall it.
There are scripts on github to reverse the change once you have done the update.
Synology supports docker containers. Just run jellyfin.
Jellyfin is also available as a native DSM package through SynoCommunity, FWIW.
To that note, anyone have any idea how to get Hyper Backup to stop telling me that my backups are “partial” because Video Station is no longer found? It’s not even on the list of apps, but tells me that it’s been disabled as an option to back up because it’s not available. Annoying!
Open hb, edit the affected backup plan, change nothing, okay/save. Happens when you set up a service to be backed up and then uninstall the service.
Brilliant! That worked!
If someone knows how to apply security updates to ancient NAS from the brand I’m interested. Sadly mine is out of the loop, I guess I’ll have to harden it like hell then
Don’t make it available from internet. This will solve the issue.
If it is not possible, once the cve is published and properly described, perhaps there is another way to secure it via an external proxy or even a waf.
If you have unsupported Sw, it is always a pain in the ass to keep them secure so try to figure out always the first point
Don’t make it available from internet. This will solve the issue.
Thanks, I’ve read this countless times but that’s basically half of the use I make from my NAS so no.
I’ll try to secure it and still use it from outside / Internet then.
Tailscale is available as an official DSM package, so if it’s only you accessing it you could still block it from the Internet.
