CVE-2024-49388

Sensitive-information modification from adjacent networks

Published Oct 15, 2024 · Updated Oct 15, 2024

Improper authorization in Acronis Cyber Protect 16 before build 38690 allows remote attackers to alter sensitive information. The vendor maps the issue to authorization bypass through a user-controlled key but does not disclose the affected component or failed authorization check. Exploitation requires adjacent-network access and high complexity, and the reported consequence is limited to sensitive-information modification.
