Lenovo advises users to remove a vulnerable, pre-installed support tool

PC maker Lenovo is recommending that users remove an application preloaded on their computers because it contains a high-severity flaw that could allow attackers to take over their systems.

The vulnerable tool is called Lenovo Accelerator Application and is designed to speed up the launch of other Lenovo applications. It was preinstalled on more than 100 laptop and desktop models shipped with Windows 10, but not those from the ThinkPad and ThinkStation lines.

The flaw was discovered by researchers from security firm Duo Security as part of an analysis of OEM software update tools from five PC manufacturers. The company found that a process called LiveAgent, apparently the update component of the Lenovo Accelerator Application, does not use encrypted connections when checking and downloading updates. LiveAgent also does not validate the digital signatures of the downloaded files before running them, the researchers said.
