CVE-2023-28291: 
vulnerability analysis and mitigation

The Raw Image Extension Remote Code Execution Vulnerability (CVE-2023-28291) is a critical security flaw affecting Microsoft's Raw Image Extension, which handles uncompressed image files before they are processed into more common formats like JPEG. The vulnerability was disclosed in April 2023 and affects Windows systems with the Raw Image Extension installed (CrowdStrike Blog, Rapid7 Blog).

The vulnerability has been assigned a CVSS base score of 8.4 (HIGH) with a vector string of CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. The vulnerability can be exploited if a victim user opens a maliciously crafted raw image file. The affected application is typically updated through the Microsoft Store, though updates can also be obtained outside the store (NVD, CrowdStrike Blog).

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the affected system with the privileges of the user who opens the malicious file. This could potentially lead to complete system compromise if the user has elevated privileges (CrowdStrike Blog).

Microsoft has released patches for this vulnerability through the Microsoft Store, where the Raw Image Extension is typically updated. Alternative updates are also available outside the store. Users should ensure their Raw Image Extension is updated to version 2.0.60612.0 or later to mitigate this vulnerability (NVD).
