CVE-2025-53395_CVE-2025-53395

7.7 / 10

HIGH

CVSS:3.1/AC:L/AV:L/A:H/C:H/I:H/PR:H/S:C/UI:R

Description

Paramount Macrium Reflect through 2025-06-26 allows local attackers to execute arbitrary code with administrator privileges via a crafted .mrimgx backup file and a malicious VSSSvr.dll located in the same directory. When a user with administrative privileges mounts a backup by opening the .mrimgx file, Reflect loads the attacker's VSSSvr.dll after the mount completes. This occurs because of untrusted DLL search path behavior in ReflectMonitor.exe.
