Executive Summary

This vulnerability is a local privilege escalation caused by DLL hijacking. It affects Acronis True Image (Windows) versions before build 42902. DLL hijacking occurs when a malicious DLL file is placed in a location where the application loads it instead of the legitimate DLL, allowing an attacker with limited privileges to execute code with higher privileges.

Impact Analysis

An attacker exploiting this vulnerability could escalate their privileges on the affected system. This means they could gain higher-level access than originally permitted, potentially leading to unauthorized access to sensitive data, modification of system settings, or installation of malicious software.
