CVE-2023-22307
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 1.6.4 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 · moderate confidenceSensitive data exposure vulnerability in the Webconf component of Tribe29 Checkmk Appliance versions prior to 1.6.4 allows a local attacker with file system access to retrieve stored passwords by reading application log files where credentials are being written in plaintext.

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.
-
Identify the Checkmk Appliance firmware versionAccess the appliance admin interface or check the system information page to determine the installed firmware version numberAffected if The firmware version is displayed as lower than 1.6.4 (for example, 1.6.0 through 1.6.3)
-
Confirm the Webconf component is enabledReview the appliance configuration or running services to verify the Webconf component is activeAffected if Webconf is currently enabled and accessible on the system
-
Locate application log filesAccess the file system and navigate to the directory where Checkmk Appliance stores its log files (typically within the application data or logs directory)Affected if Log files exist and are readable with current access permissions
-
Search log files for plaintext credentialsUse a text search utility (such as grep) to scan log files for patterns matching passwords, credentials, or sensitive data appearing in plaintextAffected if Log files contain visible plaintext passwords or credential strings
The system is affected if it runs Checkmk Appliance firmware version below 1.6.4, has the Webconf component enabled, and contains log files with plaintext credentials visible.

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 · scoped1.6.4
Update Checkmk Appliance to version 1.6.4 or later to patch the vulnerability. Additionally, audit log file access and rotate any credentials that may have been exposed.
1.6.4
- 1. Identify the current version of Checkmk Appliance Firmware by accessing the appliance management interface
- 2. Backup all critical configurations and data
- 3. Download the Checkmk Appliance Firmware version 1.6.4 or later from the official Checkmk download page
- 4. Upload the firmware upgrade via the appliance management interface
- 5. Apply the firmware update following the on-screen instructions
- 6. After upgrade, verify the version shows 1.6.4 or later
- 7. Review log file permissions and access controls to ensure no sensitive data remains exposed
