CVE-2018-16167
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 · uneditedLogonTracer 1.2.0 and earlier allows remote attackers to execute arbitrary OS commands via unspecified vectors.
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 confidenceLogonTracer versions 1.2.0 and earlier contains a critical remote command execution vulnerability (CVSS 9.8) that allows unauthenticated attackers to execute arbitrary operating system commands on the target host. The specific injection point is not detailed in the CVE, but the severe CVSS score indicates trivial exploitability.

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 LogonTracer versionLocate the LogonTracer installation and check its version metadata (such as a version file, --version output, or package manager record)Affected if The installed version is 1.2.0 or any earlier version
-
Confirm LogonTracer is runningIdentify the LogonTracer process or service on the host system and verify it is activeAffected if LogonTracer is currently running on the system
-
Assess network exposureDetermine if the LogonTracer web interface or API is accessible from network addresses other than localhostAffected if LogonTracer is listening on a network interface and accessible to unauthenticated remote users
-
Verify authentication configurationInspect LogonTracer configuration files or settings to confirm whether authentication is enabled and enforced for the web interfaceAffected if Authentication is disabled, optional, or misconfigured such that anonymous access is permitted
If LogonTracer version 1.2.0 or earlier is running and is network-accessible without authentication enforced, the environment is vulnerable to CVE-2018-16167.
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 · scopedUpgrade LogonTracer to the latest patched version immediately. If immediate patching is not feasible, restrict all network access to the LogonTracer service (e.g., firewall rules, network segmentation) to prevent unauthenticated exploitation.
Version newer than 1.2.0 (e.g., 1.2.1 or latest stable release)
- 1. Back up your current LogonTracer installation and configuration
- 2. Check the official LogonTracer GitHub repository (github.com/JPCERTCC/LogonTracer) for the latest release
- 3. Download the version newer than 1.2.0 (likely 1.2.1 or later)
- 4. Stop the LogonTracer service
- 5. Replace the existing installation with the new version
- 6. Restore your configuration from the backup
- 7. Start the LogonTracer service
- 8. Verify the service is running correctly
