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
A vulnerability in the web interface of Cisco License Manager software could allow an unauthenticated, remote attacker to download and view files within the application that should be restricted, aka Directory Traversal. The issue is due to improper sanitization of user-supplied input in HTTP request parameters that describe filenames. An attacker could exploit this vulnerability by using directory traversal techniques to submit a path to a desired file location. An exploit could allow the attacker to view application files that may contain sensitive information. Cisco Bug IDs: CSCvd83577.

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 confidence

A directory traversal vulnerability exists in the Cisco License Manager web interface. An unauthenticated, remote attacker can exploit improper sanitization of HTTP request parameters containing file paths to use traversal sequences (e.g., ../../../) and view restricted application files outside the web root directory, potentially exposing sensitive information.

MitigationApply the Cisco patch for CSCvd83577. If no patch is available, implement strict input validation on HTTP request parameters to reject directory traversal sequences and enforce proper file access controls on the application.

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. Confirm Cisco License Manager is installed
    Identify if Cisco License Manager software is present on the system. Check for the application in standard installation directories or use system inventory tools to enumerate installed Cisco software.
    Affected if Cisco License Manager version 3.2.6 is installed and running
  2. Verify the installed version
    Locate and inspect the Cisco License Manager version information, typically accessible via the application's About page, CLI show command, or installation metadata.
    Affected if The installed version is exactly 3.2.6
  3. Confirm web interface is enabled
    Check whether the Cisco License Manager web interface is accessible and running. This is typically on port 443 or 8080. Attempt to access the login page or check listening network services.
    Affected if The web interface is exposed and accepting HTTP requests on any port
  4. Review HTTP access logs for traversal patterns
    Examine web server access logs for requests containing directory traversal sequences such as ../ or ..\ in URI parameters or query strings.
    Affected if Logs show requests with traversal sequences (../../../) targeting files outside the web root

A system is affected if Cisco License Manager version 3.2.6 is running with its web interface exposed, since the vulnerability allows unauthenticated remote attackers to access restricted files via traversal sequences in HTTP requests.
