Last updated on: 2025-08-05

Assigner: MITRE

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.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability in Paramount Macrium Reflect allows a local attacker to execute arbitrary code with administrator privileges by placing a malicious VSSSvr.dll file in the same directory as a crafted .mrimgx backup file. When an administrator mounts the backup by opening the .mrimgx file, the software loads the attacker's DLL due to untrusted DLL search path behavior in ReflectMonitor.exe.


How can this vulnerability impact me? :

An attacker with local access can gain administrator-level code execution on the affected system, potentially leading to full system compromise, data loss, or unauthorized changes to system configurations.
