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
Multiple directory traversal vulnerabilities in PaperThin CommonSpot before 7.0.2 and 8.x before 8.0.3 allow remote attackers to have an unspecified impact via a filename parameter containing directory traversal sequences.

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

Multiple directory traversal vulnerabilities in PaperThin CommonSpot CMS allow remote attackers to traverse directories using '..' sequences in the filename parameter, potentially enabling unauthorized access to sensitive files outside the web root.

MitigationUpgrade to CommonSpot 7.0.2 or 8.0.3 or later to obtain the vendor patch. As a temporary control, implement strict input validation on filename parameters to reject traversal sequences and consider deploying a WAF rule to block '..' in requests.

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 if PaperThin CommonSpot CMS is installed
    Review web application fingerprinting logs, scan for CommonSpot HTTP response signatures (look for 'CommonSpot' in headers or footer content), or check the application inventory for this CMS
    Affected if CommonSpot CMS is found in the environment
  2. Determine the installed CommonSpot version
    Access the CommonSpot admin interface, check the About page, or query the version endpoint if known. Compare the version number against the affected ranges: versions <= 7.0.1, or exactly 8.0.0, 8.0.1, or 8.0.2
    Affected if The installed version matches <= 7.0.1 or equals 8.0.0, 8.0.1, or 8.0.2
  3. Locate endpoints accepting filename parameters
    Review application URL patterns and parameter usage for any feature that accepts a filename for file retrieval, download, or display operations. Common patterns include 'filename=', 'file=', or similar query parameters
    Affected if Endpoints accepting filename parameters are found and accessible without authentication
  4. Test for directory traversal vulnerability
    Send a crafted request with '..' sequences in the filename parameter (for example: ../../../../etc/passwd or ../../../config/) to identified endpoints and observe if the application returns files outside the web root
    Affected if The application returns file contents from directories outside the intended web root, confirming the traversal flaw is exploitable

The environment is affected if PaperThin CommonSpot CMS versions 7.0.1 or earlier, or versions 8.0.0 through 8.0.2 are running and endpoints accepting filename parameters are accessible without proper input sanitization.

Upgrade available Upgrade to a release after 7.0.1
Interim mitigation

Upgrade to CommonSpot 7.0.2 or 8.0.3 or later to obtain the vendor patch. As a temporary control, implement strict input validation on filename parameters to reject traversal sequences and consider deploying a WAF rule to block '..' in requests.

Recommended fix High confidence

Commonspot 7.0.2 or later (7.x branch); Commonspot 8.0.3 or later (8.x branch)

  1. 1. Identify the current Commonspot Content Server version in use by checking the server configuration or administration console.
  2. 2. If running version 7.0.1 or earlier, plan upgrade to Commonspot 7.0.2 or later.
  3. 3. If running version 8.0.0, 8.0.1, or 8.0.2, plan upgrade to Commonspot 8.0.3 or later.
  4. 4. Review PaperThin Commonspot upgrade documentation and release notes for the target version.
  5. 5. Perform a full backup of the Commonspot application, configuration files, and database before upgrading.
  6. 6. Test the upgrade in a staging environment to verify functionality.
  7. 7. Apply the upgrade in production during a planned maintenance window.
  8. 8. Verify the upgrade was successful by checking the version number and testing key functionality.
