Nasty Windows Printer Driver Vulnerability

Nasty Windows Printer Driver Vulnerability

From SentinelLabs, a critical vulnerability in HP printer drivers:

Researchers have released technical details on a high-severity privilege-escalation flaw in HP printer drivers (also used by Samsung and Xerox), which impacts hundreds of millions of Windows machines.

If exploited, cyberattackers could bypass security products; install programs; view, change, encrypt or delete data; or create new accounts with more extensive user rights.

The bug (CVE-2021-3438) has lurked in systems for 16 years, researchers at SentinelOne said, but was only uncovered this year. It carries an 8.8 out of 10 rating on the CVSS scale, making it high-severity.

Look for your printer here, and download the patch if there is one.
