NVD · uneditedSensitive information disclosure due to improper token expiration validation. The following products are affected: Acronis Agent (Windows) before build 32047.
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 confidenceImproper token expiration validation in Acronis Agent for Windows allows sensitive information disclosure. The vulnerability stems from the agent failing to properly validate token expiration times, potentially allowing expired or manipulated tokens to remain valid and expose sensitive data.

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 installedOpen Windows Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{GUID} or check Programs and Features for 'Acronis Agent' entryAffected if Acronis Agent for Windows appears in installed programs or registry
-
Identify installed Acronis Agent versionCheck the agent version through the Acronis console, or inspect the executable properties of the agent service binary (commonly in C:\Program Files\Acronis\Agent\bin\). Right-click the executable and view Details for Product VersionAffected if Product version is displayed as c23.03 or earlier, or build number is below 32047
-
Confirm agent service is activeOpen Services.msc and locate the Acronis Agent service. Verify its status is RunningAffected if The Acronis Agent service exists and is running, making token handling relevant to the environment
-
Cross-check build number against fixed versionCompare the installed build number (e.g., from the executable properties or Acronis management interface) to build 32047Affected if Installed build number is less than 32047
If Acronis Agent for Windows is installed with version c23.03 or earlier (build number below 32047), the environment is affected by improper token expiration validation.

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 32047 or later on all affected Windows systems.
Acronis Agent c23.03 (build 32047) or later
- 1. Identify the current version of Acronis Agent installed on Windows systems (check build number in the agent's About or system information)
- 2. Download Acronis Agent version c23.03 (build 32047) or later from the official Acronis download center or management console
- 3. Upgrade the Acronis Agent on all affected Windows machines to the fixed version
- 4. Verify the upgrade was successful by confirming the agent build number is 32047 or higher
