CVE-2022-45456
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDenial of service due to unauthenticated API endpoint. The following products are affected: Acronis Agent (Windows, macOS, Linux) before build 30161.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceUnauthenticated API endpoint in Acronis Agent allows remote attackers to cause denial of service. The vulnerability exists in the agent running on Windows, macOS, and Linux systems before build 30161, where the API lacks proper authentication controls enabling resource exhaustion.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Acronis Agent is installedCheck for Acronis Agent service or process on the system. On Windows, run 'Get-Service' or check Program Files for Acronis directory. On Linux/macOS, check for 'acronis' processes or look in /opt/Acronis or /Applications.Affected if Acronis Agent software is present on the system
-
Identify installed Acronis Agent version and build numberLocate the installed version information. On Windows, check the agent's About or version dialog, or examine the executable properties. On Linux/macOS, check the agent binary or configuration files for version strings like 'c22.08' or build numbers.Affected if Version shows c22.08 or earlier, or build number is below 30161
-
Confirm the management API service is enabled and listeningCheck if the Acronis management API service is running and bound to a network port (typically ports 9850 or 8443 for Acronis Agent). Use netstat or equivalent to identify listening services.Affected if The Acronis Agent API service is actively listening on network ports
-
Test for unauthenticated API accessSend a simple HTTP request to the local agent API endpoint (such as /api/v1/health or similar unauthenticated endpoint) without providing credentials. Observe if the API responds without rejecting the request.Affected if The API responds to unauthenticated requests with valid data rather than requiring authentication
A system is affected if Acronis Agent is installed with version c22.08 or earlier (build below 30161) and the management API service is running and accessible without authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade Acronis Agent to build 30161 or later on all affected Windows, macOS, and Linux endpoints to remediate the unauthenticated API vulnerability.
c22.08 (Agent build 30161 or later)
- Upgrade Acronis Agent to version c22.08 or later (build 30161 or higher)
- Verify the upgrade was successful by checking the agent build number in the Acronis management console
- Confirm the unauthenticated API endpoint is no longer accessible without authentication
