CVE-2023-28291

Arbitrary code execution via improper input validation

Published Apr 11, 2023 · Updated Jan 23, 2025

Improper input validation in Microsoft Raw Image Extension 2.1.0.0 through 2.1.60610.0 allows local users to execute arbitrary code. Microsoft has not published the affected parser, input format, or validation operation performed incorrectly. Exploitation requires local access but no privileges or user interaction, and successful exploitation runs attacker-controlled code in the affected process.
