CVE-2022-45456

Service interruption via unauthenticated API endpoint

Published Apr 26, 2023 · Updated Jan 30, 2025

Denial of service in Acronis Agent before build 30161 allows local users to interrupt the agent through an unauthenticated API endpoint. Acronis identifies the exposed API endpoint as the locus but has not disclosed its path or the request-handling error that causes the interruption. Local access is required under the vendor's assessment; public material does not specify whether the result is a hang, crash, or restart.
