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
An insertion of sensitive information into log file vulnerability in Fortinet FortiGuest 1.0.0 allows a local attacker to access plaintext passwords in the RADIUS logs.

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 · high confidence

FortiGuest 1.0.0 logs RADIUS authentication requests including plaintext passwords, allowing a local attacker with file system access to read sensitive credential data from the log files.

MitigationApply vendor patch when available; in the interim, restrict file system access to authorized administrators only and audit/revoke any potentially exposed credentials.

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 FortiGuest installation and version
    Locate the FortiGuest installation directory and check the installed version (expected: 1.0.0). Use system package manager or check application metadata files if available.
    Affected if FortiGuest version 1.0.0 is installed on the system.
  2. Confirm RADIUS authentication is configured
    Check FortiGuest configuration for RADIUS authentication settings. Look for RADIUS server definitions, shared secrets, and user authentication methods pointing to RADIUS.
    Affected if RADIUS authentication is enabled and users authenticate via RADIUS.
  3. Locate FortiGuest log files
    Find FortiGuest log directory - typically within the application installation path or system logging location. Search for log files with names indicating authentication or RADIUS activity.
    Affected if Log files exist in the FortiGuest environment.
  4. Inspect logs for plaintext passwords
    Open recent FortiGuest authentication logs and search for plaintext password strings in RADIUS authentication entries. Look for patterns like 'password=', 'Password:', or visible credential data in auth request records.
    Affected if Log files contain RADIUS authentication entries with plaintext (not hashed or masked) password data.

The environment is affected if FortiGuest 1.0.0 is running with RADIUS authentication enabled and log files contain plaintext passwords in authentication records.

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.
