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
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Komtera Technolgies KLog Server allows Manipulating Web Input to File System Calls. This issue affects KLog Server: before 3.1.1.

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 confidence

A path traversal vulnerability exists in KLog Server where user-supplied web input is not properly validated before being used in file system operations. An attacker could manipulate input to access files outside the intended directory using directory traversal sequences (e.g., ../).

MitigationUpgrade KLog Server to version 3.1.1 or later, which contains the fix for this vulnerability. If upgrading is not immediately possible, implement strict input validation and whitelist-based file access controls.

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 KLog Server version
    Locate the KLog Server installation and check the version metadata (typically in an about page, version file, or executable properties). Compare to the affected range (versions prior to 3.1.1).
    Affected if Installed version is before 3.1.1
  2. Verify file operation features are in use
    Review KLog Server configuration or audit which web-facing features accept file path inputs (such as log file loading, export, or report generation functions).
    Affected if File operation features that accept user input are enabled and accessible via the web interface
  3. Check for input validation mechanisms
    Examine KLog Server configuration files or code for any input validation, sanitization, or allowlist logic applied to file path parameters in web requests.
    Affected if No input validation is configured for file path parameters, or validation can be bypassed
  4. Review access controls on file operations
    Inspect KLog Server role permissions or access control settings to determine if file operations are restricted to privileged users or are publicly accessible.
    Affected if File operation endpoints are accessible to unauthenticated or low-privilege users
  5. Audit web request logs for traversal attempts
    Examine KLog Server web access logs or application logs for patterns containing '../' or other directory traversal sequences in file path parameters.
    Affected if Log entries show directory traversal sequences in requests to file-related endpoints

A user is affected if KLog Server version is prior to 3.1.1 AND file operation features accepting web input are enabled without proper input validation.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade KLog Server to version 3.1.1 or later, which contains the fix for this vulnerability. If upgrading is not immediately possible, implement strict input validation and whitelist-based file access controls.

Recommended fix Moderate confidence

KLog Server 3.1.1

  1. Backup the current KLog Server installation and its database before proceeding with the upgrade
  2. Download KLog Server version 3.1.1 from the official Komtera Technologies vendor website or trusted distribution channel
  3. Stop the KLog Server service to ensure a clean upgrade process
  4. Follow the vendor's documented upgrade procedure for KLog Server version 3.1.1
  5. After upgrade, verify that the Path Traversal vulnerability is resolved by testing that file system access is properly restricted
  6. Restart the KLog Server service
