The ever-lasting game between researchers and hackers continues with the recent discovery of a major flaw found within the Dell SupportAssist . The comes pre-installed on a large number of devices, and its goal is to do regular checks of the health of and hardware. To do these checks, the SupportAssist needs to have full access to the system, which gives it permissions to access any part of the device.

As mentioned, this includes software and
hardware alike, including the physical memory of devices, their SMBios, and
more. As such, SupportAssist can also put users in an incredible amount of
danger if anyone managed to access it remotely, which is just what the
newly-discovered vulnerability allows.

A major vulnerability once again
puts millions in danger

The flaw was originally discovered by a
firm SafeBreach Labs. As a part of a pre-installed program on the
majority of -branded devices, it is extremely risky, and it is estimated
that it endangers over 100 million people.

SafeBreach Labs reported that the flaw comes from a lack of authentication when the system attempts to pull library files from various folders and interact with them. In other words, the program does not try to verify if the libraries are legitimate or not. This would allow skilled hackers to trick it by placing an infected file into a folder that SupportAssist would later try to interact with.

As soon as the file is scanned and activated, the trap would spring, compromising the entire system, and exposing users’ private information. Of course, in order for this to happen, the hacker would first have to trick the user into downloading the malicious file. But, if successful, they would be granted access to the device’s entire system after SupportAssist activates the trap.

This was confirmed by SafeBreach Labs’
security researcher, Peleg Hadar. Hadar noted that the attacker could do
whatever they wanted after gaining control of the system. Not only that, but
the vulnerability might be affecting a number of different devices.

Since SupportAssist was made by the PC-Doctor
and has become highly popular among many different brands — many have
also rebranded it, while keeping the same vulnerable component. Some of its
versions include CORSAIR Diagnostics, Tobii Dynavox Diagnostics Tool, CORSAIR
ONE Diagnostics, Staples EasyTech Diagnostics, and others.

Even the laptops such as MSI, or Acer, which
use Tobii and Corsair products are likely to have the same vulnerability. The
same is true for any other device that has been serviced by Staples employees,
as they have likely used this piece of software for checking the devices’
health.

The patch is out

The severity of the flaw is massive, and it
goes without saying that it could mean a huge danger for millions of people
around the world. However, the situation is not as bad as it might seem at
first, as the Dell reacted very quickly, and released a patch that fixes the
issues.

The patch went live on May 28th, and it was
successfully installed by over 90% of users, according to Dell. However, that
still leaves 10% of users exposed, and in danger of having their device
compromised. The successful adoption of the patch is the result of automatic
updates, which dell leaves enabled by default.

With that said, there are cases where the automatic updates were either not enabled, or purposefully disabled by users. In these cases, the users are vulnerable, as they might not be aware of the patch, if they don’t regularly check for one. Users who do not remember having their devices updated recently should download and install the patch manually as soon as possible.

Those who might not be sure whether or not their device was patched can install it manually anyway. If the device was already patched, there would be no harm done. If it was not, the device would finally be safe from harm once again. The patch is easily accessible on SupportAssist’s download page.
