Description
Macrium Reflect includes an OpenSSL component that specifies an OPENSSLDIR variable as C:\openssl\. Macrium Reflect contains a privileged service that uses this OpenSSL component. Because unprivileged Windows users can create subdirectories off of the system root, a user can create the appropriate path to a specially-crafted openssl.cnf file to achieve arbitrary code execution with SYSTEM privileges.
Affected products
- Macrium Reflect: before 7.3.5281 — fixed in 7.3.5281
How to fix
Upgrade to a fixed version: Macrium Reflect 7.3.5281. Check the vendor advisory for mitigations.
