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
A sensitive information exposure vulnerability in System Information Reporter (SIR) 1.0.3 and prior allows an authenticated non-admin local user to extract sensitive information stored in a registry backup folder.

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

A local information disclosure vulnerability in System Information Reporter (SIR) 1.0.3 and prior allows an authenticated non-admin user to access sensitive information stored in a registry backup folder that should be restricted to administrators only.

MitigationImplement proper filesystem access controls on the registry backup folder to ensure only administrative users can read sensitive registry 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 checks

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

  1. Verify SIR installation
    Check for Trellix System Information Reporter installation via system inventory, program files directory, or running process list
    Affected if Trellix SIR is installed on the system
  2. Determine SIR version
    Locate SIR version via 'Help > About', installed programs list, or executable file properties
    Affected if Version is 1.0.3 or prior
  3. Identify registry backup folder location
    Locate the registry backup folder used by SIR - typically found in the SIR data or config directory
    Affected if Registry backup folder exists on the system
  4. Verify folder access permissions
    Inspect filesystem permissions on the registry backup folder to determine if non-administrative users have read access
    Affected if Non-admin authenticated users can read contents of the registry backup folder

Environment is affected if Trellix System Information Reporter version 1.0.3 or prior is installed AND the registry backup folder is readable by authenticated non-administrative users.

Upgrade available Upgrade to a release after 1.0.3
Interim mitigation

Implement proper filesystem access controls on the registry backup folder to ensure only administrative users can read sensitive registry data.
