CVE-2023-45244

Sensitive data read and alteration via missing authorization

Published Oct 6, 2023 · Updated Aug 2, 2024

Missing authorization in affected Acronis Cyber Protect products allows local users to read and alter sensitive information on the host. Acronis has not disclosed the affected component, missing authorization check, or operation that mishandles the requesting user's privileges. Low-privileged local access is required in Cloud Agent before build 35895 or Cyber Protect 16 before build 37391; exploitation compromises confidentiality and integrity without interrupting service.
