CVE-2023-41676
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 · uneditedAn exposure of sensitive information to an unauthorized actor [CWE-200] in FortiSIEM version 7.0.0 and before 6.7.5 may allow an attacker with access to windows agent logs to obtain the windows agent password via searching through the 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 confidenceIn FortiSIEM versions 7.0.0 and before 6.7.5, Windows agent passwords are being logged in plaintext within Windows agent logs. An attacker with access to these logs can retrieve the 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 checksWork through these to decide whether this CVE applies to you.
-
Check FortiSIEM versionRun the command to display the FortiSIEM version, typically via 'phstatus' or checking the GUI About pageAffected if Version is 7.0.0 or between 6.7.0 and 6.7.5 (inclusive)
-
Locate Windows agent log filesIdentify the directory where FortiSIEM stores Windows agent logs - typically found in the FortiSIEM installation directory under logs or a dedicated agent log pathAffected if Log directory exists and contains Windows agent logs
-
Search logs for plaintext passwordsUse grep, strings, or a text search utility to search the Windows agent log files for patterns matching Windows credentials or password-like strings (such as 'password=', 'pwd=', or domain/user credentials in plaintext)Affected if Log files contain plaintext password strings or credential data in readable form
-
Check log retention settingsReview FortiSIEM log retention and export configurations to determine if logs containing potential plaintext credentials have been archived or exportedAffected if Old logs with plaintext credentials may still be accessible in archives or exports
You are affected if your FortiSIEM version falls within 6.7.0-6.7.5 or equals 7.0.0 AND your Windows agent logs contain plaintext passwords or credentials.
Generated from the published advisory. Verify against your own configuration.
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 · scopedConfigure FortiSIEM to mask or exclude sensitive credentials from log output, and rotate the exposed Windows agent passwords as a precaution.
FortiSIEM 6.7.6 or later, or FortiSIEM 7.0.1 or later (recommended: latest stable release)
- 1. Identify the current FortiSIEM version by navigating to Admin > System Settings > System Control in the FortiSIEM GUI
- 2. Download the latest FortiSIEM release from Fortinet customer support portal or FortiGuard
- 3. Plan the upgrade during a maintenance window to minimize business impact
- 4. Back up the current FortiSIEM configuration and database
- 5. Run the upgrade installer following Fortinet's official upgrade documentation
- 6. After upgrade, verify the Windows agent password is no longer exposed in logs
- 7. Review agent logs to confirm the sensitive information exposure has been resolved
