CVE-2010-2786
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 · uneditedDirectory traversal vulnerability in Piwik 0.6 through 0.6.3 allows remote attackers to include arbitrary local files and possibly have unspecified other impact via directory traversal sequences in a crafted data-renderer request.
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 confidencePiwik versions 0.6 through 0.6.3 contain a directory traversal vulnerability in the data-renderer component. Attackers can use '../' sequences in crafted requests to traverse the filesystem and include arbitrary local files, potentially exposing sensitive configuration files, credentials, or system files.

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 installed Piwik/Matomo versionLocate the version file in the Piwik/Matomo installation directory. Common paths include 'piwik/version.php' or 'matomo/version.php'. Open the file and read the version number defined in the version variable.Affected if The installed version is 0.6, 0.6.1, 0.6.2, or 0.6.3.
-
Locate the data-renderer componentSearch for the 'data-renderer' file in the Piwik/Matomo installation. Common paths include 'libs/data_renderer.php' or within the 'libs/' directory. Verify the file exists in the installation.Affected if The data-renderer component is present in the installation.
-
Verify data-renderer is accessible via webAttempt to access the data-renderer component through the web server using a standard Piwik URL path such as '/libs/data_renderer.php' or check the web server access logs for requests to this component.Affected if The data-renderer component is accessible via HTTP/HTTPS requests.
-
Test for directory traversal vulnerabilitySend a crafted request to the data-renderer component with '../' sequences in parameters, such as '?url=../../../../etc/passwd' or similar path parameters. Inspect the response for file contents or error messages revealing successful traversal.Affected if The application returns content from files outside the web root or displays path traversal errors.
A user is affected if they are running Piwik/Matomo version 0.6 through 0.6.3 AND the data-renderer component is accessible and vulnerable to directory traversal via '../' sequences in requests.

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.
From vendor dataUpgrade to Piwik version 0.6.4 or later, which includes input validation fixes for the data-renderer parameter. Alternatively, implement strict whitelist-based input validation on all file path parameters to reject directory traversal sequences.
