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 · unedited
Sensitive information disclosure due to missing authorization. The following products are affected: Acronis Agent (Linux, macOS, 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 confidence

Acronis Agent versions prior to build 32047 contain a missing authorization vulnerability that allows sensitive information disclosure. An unauthenticated or improperly authorized attacker could potentially access sensitive data due to the lack of proper authorization controls in the affected Agent components running on Linux, macOS, and Windows platforms.

MitigationUpgrade Acronis Agent to build 32047 or later to implement proper authorization checks and prevent unauthorized access to sensitive information.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Acronis Agent is installed
    Linux: run 'dpkg -l | grep -i acronis' or 'rpm -qa | grep -i acronis'. macOS: check '/Applications' for Acronis folder or run 'ls /Library/Application Support/Acronis'. Windows: check 'Programs and Features' or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where-Object {$_.DisplayName -like "*Acronis*"}'
    Affected if Acronis Agent is found installed on the system
  2. Determine the installed build version
    Linux: run 'rpm -qi <agent-package-name>' or check '/usr/lib/Acronis/version'. macOS: right-click Acronis Agent.app in /Applications, select Get Info, or run '/Library/Application Support/Acronis/Agent/version'. Windows: right-click the Acronis Agent executable in Program Files, select Properties, or check the registry key 'HKLM\SOFTWARE\Acronis\Agent\Version'
    Affected if The build version returned is less than 32047 (or version shows c23.03 or earlier)
  3. Verify the Agent service is running and accessible
    Linux: run 'systemctl status acronis_agent' or 'ps aux | grep acronis'. macOS: run 'launchctl list | grep -i acronis' or check Activity Monitor. Windows: open Services and check if 'Acronis Agent' service status is Running, or run 'Get-Service -Name *Acronis*'
    Affected if The Acronis Agent service is running and exposed on the network (default ports 9877, 443, or 8443)
  4. Check network exposure of management interface
    Linux/macOS: run 'netstat -tlnp | grep -E "(9877|8443)"' to check if agent ports are listening. Windows: run 'netstat -an | findstr "9877"' or use PowerShell 'Get-NetTCPConnection -LocalPort 9877,8443 -State Listen'
    Affected if The Acronis Agent management port is listening on a network interface accessible to untrusted users or the internet

The system is affected if Acronis Agent is installed with a build version earlier than 32047 (or c23.03) and the management interface is network-accessible, allowing potential unauthorized sensitive data access.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Acronis Agent to build 32047 or later to implement proper authorization checks and prevent unauthorized access to sensitive information.

Recommended fix Moderate confidence

Acronis Agent c23.03 (build 32047)

  1. Obtain Acronis Agent c23.03 (build 32047) from the official Acronis download center or your licensed Acronis account portal
  2. Stop the Acronis Agent service on affected Linux, macOS, or Windows systems
  3. Upgrade the Acronis Agent installation to version c23.03 (build 32047) using the standard upgrade procedure for your platform
  4. Restart the Acronis Agent service and verify the upgrade was successful
