Microsoft has warned of yet another vulnerability that’s been discovered in its Windows Print Spooler that can allow attackers to elevate privilege to gain full user rights to a system. The advisory comes on the heels of patching two other remote code-execution (RCE) bugs found in the print service that collectively became known as PrintNightmare.
The company released the advisory late Thursday for the latest bug, a Windows Print Spooler elevation-of-privilege vulnerability tracked as CVE-2021-34481. Microsoft credited Dragos vulnerability researcher Jacob Baines for identifying the issue.
