What to do
AI-suggested
European organizations should prioritize upgrading affected Acronis Cyber Protect Cloud Agent versions to the fixed builds (build 39185 or later for the Cloud Agent and build 39938 or later for Acronis Cyber Protect 16) as soon as patches become available. Until patches are released, organizations should restrict local access to Linux systems running Acronis agents to trusted administrators only, enforce strict privilege management, and monitor for unusual package installation activities. Implementing additional integrity verification mechanisms, such as out-of-band verification of package signatures or using alternative trusted package repositories, can help mitigate risks. Regular auditing of installed packages and anomaly detection on endpoint systems can also provide early warning of tampering attempts. Network segmentation to isolate critical Linux systems and limiting software installation capabilities to authorized personnel will further reduce exploitation likelihood. Finally, organizations should maintain up-to-date threat intelligence feeds to detect any emerging exploit attempts targeting this vulnerability.
Description
Weak algorithm used to sign RPM package. The following products are affected: Acronis Cyber Protect Cloud Agent (Linux) before build 39185, Acronis Cyber Protect 16 (Linux) before build 39938.
