Synology has released security updates to address a critical bug affecting VPN Plus Server that could be exploited to take over affected systems.
The vulnerability tracked as CVE-2022-43931 has a maximum severity rating of 10 on the CVSS scale and has been described as an out-of-bounds write error in the remote desktop functionality in Synology VPN Plus Server.
Successful exploitation of the issue “allows remote attackers to execute arbitrary commands via unspecified vectors,” the Taiwanese company said, adding that it was discovered internally by its Product Security Incident Response Team (PSIRT).
VPN Plus Server for Synology Router Manager (SRM) 1.2 and VPN Plus Server for SRM 1.3 users are recommended to update to versions 1.4.3-0534 and 1.4.4-0635, respectively.
In a second advisory, the manufacturer of network-attached storage appliances also warned of several flaws in SRM that could allow remote attackers to execute arbitrary commands, carry out denial-of-service attacks or read arbitrary files.
Full details of the vulnerabilities have been withheld, urging users to update to versions 1.2.5-8227-6 and 1.3.1-9346-3 to mitigate potential threats.
Gaurav Baruah, CrowdStrike’s Lukas Kupczyk, DEVCORE researcher Orange Tsai and Dutch IT security firm Computest have been blamed for reporting the vulnerabilities.
It is worth noting that some of the vulnerabilities were demonstrated at the Pwn2Own 2022 contest, which took place between December 6th and 9th, 2022 in Toronto, Canada.
Baruah earned $20,000 for a command-injection attack on the Synology RT6600ax’s WAN interface, while Computest received $5,000 for a command-injection root shell exploit that targeted its LAN interface.

Best Answer: An SSD cache provides much better performance for select read/write intensive workloads, such as running a database or a virtual machine on your NAS.
How much RAM does Plex need?
In general, Plex Media Server does not require large amounts of RAM. 2GB of RAM is usually more than enough, and some installs (especially Linux-based installs) can often run fine with even less.
Is RAM important for a media server? RAM doesn’t make a significant difference in a media server’s performance. Faster RAM can help speed things up a bit. Overall, though, you don’t need a lot of RAM since most streaming platforms don’t use a lot.
How much RAM does Plex reddit need?
Plex says it’s very RAM efficient and can run with 2GB.
How much RAM does my server need?
The starting point for different projects can vary from 8GB to 64GB of server RAM depending on the project requirements.
Can I upgrade the memory in Synology DS220+?
The Synology DiskStation DS220 is a very powerful mid-range NAS enclosure. Not only is it equipped with an Intel processor and two drive bays, but it also has upgradeable DDR4 RAM. This allows you to increase the pre-installed capacity from 2 GB to a total of 6 GB.
What RAM works with DS920+? The type of memory you need to buy for your Synology NAS device DS920 is Samsung 8GB DDR4 CL19 2666MHz Product Code: M471A1K43CB1-CTD or official Synology RAM module D4NESO-2666-4G. In fact, these RAM modules are compatible with both Synology DS920 and DS720.
Can I add more RAM to my Synology NAS?
The best Synology NAS cases make it easy to upgrade the RAM modules. Most NAS models released in the last three years come with expandable memory, and if you run into trouble multitasking on the NAS or need to use virtual machines, you can always increase the memory.
Can I add RAM to the Synology DS220j?
Unfortunately, you cannot replace or upgrade the memory of the following Synology models: Synology DS218play. Synology DS220j.
What memory does the DS220+ need?

Is Synology SHR better than RAID?
Using the same example as before, SHR is able to split the 4.5TB of unavailable storage into smaller usable blocks and maximize the storage capacity of each drive. SHR also outperforms classic RAID when it comes to memory expansion.
Which is better SHR or RAID 5? Finally, an SHR array can be created with at least two hard drives with full drive failure protection. On the other hand, RAID 5 requires at least three hard drives to be installed. This is a big difference as many people are not going to fill their NAS with hard drives right away.
Is SHR faster than RAID?
Like traditional RAID, SHR gives you the option to protect your data from losing a single hard drive or SSD. However, with SHR-2 you are protected from losing 2 HDDs or SSDs. Slightly less speed than a traditional RAID. Less than 1% difference e.g. B. between SHR and RAID 5.
Is SHR better than RAID 1?
In contrast to classic RAID, SHR divides the storage space of each drive into smaller blocks and creates additional redundant storage. SHR also outperforms classic RAID when it comes to memory expansion. SHR, on the other hand, enables storage pool expansion immediately after upgrading two drives and can form redundant storage arrays.
Can NAS be hacked?
Unfortunately, NAS drives can also pose a security risk. By connecting your hard drives to a network, you could give hackers access. Attacks on NAS are common in business environments, and while attacks on individuals are less profitable, they still happen.
How do I restrict access to my NAS? How to restrict user access to NAS Shared subfolders…
- Go to Control Panel > Privilege > Shared Folders > Advanced Privileges tab.
- Check the option “Enable advanced folder permissions”.
- Click Apply.
How secure is Synology NAS?
Synology DSM has been thoroughly tested and certified with FIPS 140 for cryptographic modules and OpenChain 2.0 and 2.1 for open source compliance. It also uses industry-standard AES-256 encryption to protect your files.
Are NAS devices secure?
As with most network devices, cyber criminals always seem to succeed and eventually gain access to them. This means that no NAS device is secure after a few months and the administrator should update or patch it regularly. Include NAS devices in regular update plans and procedures so that their firmware is protected as soon as possible.
