CVE-2023-6287
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 · uneditedSensitive data exposure in Webconf in Tribe29 Checkmk Appliance before 1.6.8 allows local attacker to retrieve passwords via reading log files.
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 Tribe29 Checkmk Appliance before version 1.6.8, the Webconf component writes sensitive information, including passwords, to log files in plaintext. A local attacker with file system access can read these log files to retrieve 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.
-
Determine Checkmk Appliance firmware versionAccess the appliance management interface or check the system information page to identify the installed firmware version.Affected if version is below 1.6.8
-
Identify Webconf component usageDetermine if the Webconf component is enabled or configured on the appliance. Check the component status through the appliance admin interface.Affected if Webconf is enabled or configured
-
Locate Webconf log filesSearch the filesystem for log files generated by the Webconf component. Common locations may include /var/log/ or appliance-specific log directories.Affected if Webconf log files exist on the system
-
Inspect log files for plaintext credentialsOpen the identified Webconf log files and search for patterns that indicate plaintext passwords, such as 'password=', 'passwd=', or visible credential strings.Affected if log files contain plaintext passwords or other sensitive credentials
-
Verify log file permissionsCheck file permissions on the Webconf log files to determine if unauthorized local users can read them (e.g., world-readable permissions).Affected if log files are readable by non-privileged or unauthorized users
A user is affected if the installed Checkmk Appliance firmware is below version 1.6.8, the Webconf component is active, and its log files contain plaintext passwords accessible to unauthorized users.

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 · scoped1.6.8
Upgrade the Checkmk Appliance to version 1.6.8 or later to remediate the vulnerability. Until then, restrict local access and monitor log file permissions.
Checkmk Appliance Firmware 1.6.8
- Backup the current Checkmk Appliance configuration and data
- Download Checkmk Appliance Firmware version 1.6.8 or later from the official Checkmk download repository
- Access the Checkmk Appliance management interface
- Navigate to the firmware update section
- Upload and apply the downloaded firmware file
- Follow the on-screen prompts to complete the upgrade process
- After upgrade, verify the version number reflects 1.6.8 or later
- Review updated log files to confirm passwords are no longer being exposed in plain text
