SentinelLabs says that, while its testing was limited to a handful of vendors, others relying on the same vulnerable libraries might be impacted as well. Security updates have been released to patch all of the identified vulnerabilities, with some of the fixes being automatically applied. SentinelLabs reported the vulnerabilities to the vendors in the second quarter of the year, which has resulted in a total of 27 CVE identifiers being issued.Īffected products include Amazon’s Nimble Studio AMI, NICE DCV, WorkSpaces, and AppStream client Accops’ HyWorks Client and HyWorks DVM Tools for Windows Amzetta zPortal (Windows client and DVM Tools) Donglify Eltima USB Network Gate FlexiHub and NoMachine. “These vulnerabilities allow attackers to escalate privileges enabling them to disable security products, overwrite system components, corrupt the operating system, or perform malicious operations unimpeded,” the security researchers explain. ![]() SentinelLabs discovered the security holes in I/O Control (IOCTL) handlers in charge of “validating, probing, locking, and mapping the buffer itself depending on the use case,” and which are the same across all vulnerable products.īecause of the manner in which the handlers are used and because no buffer verification exists, malicious attackers could look for double fetches and arbitrary pointer dereference, which in turn could lead to other vulnerabilities. Responsible for the redirection are two drivers that are flawed, and which might have been vulnerable since the beginning of 2020, SentinelLabs researchers say. In Amazon WorkSpaces, SentinelOne’s SentinelLabs explains, the library allows users to redirect USB devices so they can connect them directly from a remote desktop. The issues were identified in an Eltima product called ‘USB Over Ethernet’, which provides remote USB redirection functionality and which is implemented in some cloud products with several modifications. ![]() Potentially serious vulnerabilities identified in a library developed by Eltima affected multiple cloud services, according to endpoint security company SentinelOne.
