DescriptionCVE.org

Sensitive data disclosure and manipulation due to missing authorization. The following products are affected: Acronis Cyber Protect 16 (Linux, Windows) before build 39938, Acronis Cyber Protect 15 (Linux, Windows) before build 41800.

Executive ViewAI

Why It Matters

A critical vulnerability in Acronis Cyber Protect 15 and 16 allows unauthorized access to sensitive data and unauthorized modifications without a patch currently available. Organizations using affected versions face immediate risk of data breach and system compromise affecting backup and disaster recovery infrastructure.

Business Impact: Severe

Compensating Controls

Network segmentation: restrict administrative access to Acronis systems via firewall rules and VLANs; disable remote access to Acronis interfaces if not operationally critical; implement strict access controls limiting user privileges to minimum required; enable comprehensive audit logging on all Acronis instances; monitor API calls and data access patterns for anomalies; consider temporary suspension of non-critical backup operations until patch available.
