Owners of older Lenovo laptops need to uninstall the Lenovo Solution Center as soon as possible. 
Security researchers at Pen Test Partners found a critical vulnerability in the Lenovo Solution Center that could hand admin privileges over to hackers or malware.
According to Pen Test Partners, the flaw is a discretionary access control list (DACL) overwrite, which means a low-privileged user can sneak into a sensitive file by exploiting a high-privileged process. This is an example of a "privileged escalation" attack in which a bug can be used to gain access to resources that are normally only accessible to admins.
In this case, an attacker could write a pseudo-file (called a hard link file) that, when run by Lenovo Solution Center, would access sensitive files it otherwise shouldn't be allowed to reach. From there, damaging code could be executed on the system with administrator or system privileges, which is basically game over, as Pen Test Partners notes.
Lenovo Solution Center is a program that was preinstalled on Lenovo laptops from 2011 up until November 2018, which means millions of devices could be affected. Ironically, the program's purpose is to monitor the health and security of a Lenovo PC. While this flaw isn't such a big concern for individual users who can quickly protect their systems, larger companies who own a fleet of older ThinkPad laptops and use legacy software might be slow to react.
For its part, Lenovo published a security statement warning users about the bug and urging them to uninstall Solution Center, which the company no longer supports.
"A vulnerability reported in Lenovo Solution Center version 03.12.003, which is no longer supported, could allow log files to be written to non-standard locations, potentially leading to privilege escalation. Lenovo ended support for Lenovo Solution Center and recommended that customers migrate to Lenovo Vantage or Lenovo Diagnostics in April 2018," reads the statement.
