AI-suggested
Organizations should prioritize upgrading Acronis Cyber Protect 16 to build 39938 or later once the vendor releases a patch addressing this vulnerability. If you cannot patch yet, network segmentation should be enforced to limit access to the Acronis management interfaces and backup servers to trusted hosts only, reducing the risk of adjacent network attackers. Employing strict access controls, including network-level authentication and firewall rules, can help prevent unauthorized lateral movement. Monitoring network traffic for unusual TLS handshake anomalies or unexpected certificate/key usage may provide early detection of exploitation attempts. Additionally, organizations should review and strengthen their cryptographic policies and configurations, ensuring that only strong, industry-standard cryptographic algorithms and key lengths are used across all systems. Conducting regular vulnerability assessments and penetration tests focusing on backup infrastructure can help identify weaknesses. Finally, maintaining comprehensive incident response plans that include backup integrity verification procedures will aid in rapid detection and recovery if exploitation occurs.
Description
Weak server key used for TLS encryption. The following products are affected: Acronis Cyber Protect 16 (Linux, macOS, Windows) before build 39938.
