An authenticated remote code execution vulnerability exists in Piwik (now Matomo) versions prior to 3.0.3 via the plugin upload mechanism. In vulnerable versions, an authenticated user with Superuser privileges can upload and activate a malicious plugin (ZIP archive), leading to arbitrary PHP code execution on the underlying system. Starting with version 3.0.3, plugin upload functionality is disabled by default unless explicitly enabled in the configuration file.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Drupal Piwik PRO allows Cross-Site Scripting (XSS).This issue affects Piwik PRO: from 0.0.0 before 1.3.2.

Cross-Site Request Forgery (CSRF) vulnerability in Drupal Matomo Analytics allows Cross Site Request Forgery. This issue affects Matomo Analytics: from 0.0.0 before 1.24.0.

Cross-Site Request Forgery (CSRF) vulnerability in matomoteam Matomo Analytics matomo allows Cross Site Request Forgery.This issue affects Matomo Analytics: from n/a through <= 5.1.1.

The Matomo Analytics – Ethical Stats. Powerful Insights. plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the idsite parameter in all versions up to, and including, 4.15.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Cross-Site Scripting

The official piwik Docker images before fpm-alpine (Alpine specific) contain a blank password for a root user. Systems using the Piwik Docker container deployed by affected versions of the Docker image may allow an remote attacker to achieve root access.

Cross-site Scripting (XSS) in Piwik before 1.10.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: This is a different vulnerability than CVE-2013-0193 and CVE-2013-0194.

Cross-site Scripting (XSS) in Piwik before 1.10.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: This is a different vulnerability than CVE-2013-0193 and CVE-2013-0195.

Cross-site Scripting (XSS) in Piwik before 1.10.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: This is a different vulnerability than CVE-2013-0194 and CVE-2013-0195.

DISPUTED A full path disclosure vulnerability was discovered in Matomo v3.9.1 where a user can trigger a particular error to discover the full path of Matomo on the disk, because lastError.file is used in plugins/CorePluginsAdmin/templates/safemode.twig. NOTE: the vendor disputes the significance of this issue, stating "avoid reporting path disclosures, as we don't consider them as security vulnerabilities."

Directory traversal vulnerability in core/ViewDataTable/Factory.php in Piwik before 2.15.0 allows remote attackers to include and execute arbitrary local files via the viewDataTable parameter.

The DisplayTopKeywords function in plugins/Referrers/Controller.php in Piwik before 2.15.0 allows remote attackers to conduct PHP object injection attacks, conduct Server-Side Request Forgery (SSRF) attacks, and execute arbitrary PHP code via a crafted HTTP header.

Piwik before 1.11 accepts input from a POST request instead of a GET request in unspecified circumstances, which might allow attackers to obtain sensitive information by leveraging the logging of parameters.

Cross-site scripting (XSS) vulnerability in Piwik before 1.11 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Cross-site scripting (XSS) vulnerability in Piwik before 1.9 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Unspecified vulnerability in Piwik 1.2 through 1.4 allows remote attackers with the view permission to execute arbitrary code via unknown attack vectors.

Piwik 1.1 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by plugins/Widgetize/Widgetize.php and certain other files.

Multiple cross-site scripting (XSS) vulnerabilities in Piwik before 1.1 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Piwik before 1.1 does not prevent the rendering of the login form inside a frame in a third-party HTML document, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site.

Piwik before 1.1 does not properly limit the number of files stored under tmp/sessions/, which might allow remote attackers to cause a denial of service (inode consumption) by establishing many sessions.

The PiwikCommon::getIP function in Piwik before 1.1 does not properly determine the client IP address, which allows remote attackers to bypass intended geolocation and logging functionality via (1) use of a private (aka RFC 1918) address behind a proxy server or (2) spoofing of the X-Forwarded-For HTTP header.

Cookie.php in Piwik before 1.1 does not set the secure flag for the session cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

Directory 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.

Cross-site scripting (XSS) vulnerability in the Login form in Piwik 0.1.6 through 0.5.5 allows remote attackers to inject arbitrary web script or HTML via the formurl parameter.

The loadContentFromCookie function in core/Cookie.php in Piwik before 0.5 does not validate strings obtained from cookies before calling the unserialize function, which allows remote attackers to execute arbitrary code or upload arbitrary files via vectors related to the destruct function in the PiwikConfig class; php://filter URIs; the destruct functions in Zend Framework, as demonstrated by the ZendLog destructor; the shutdown functions in Zend Framework, as demonstrated by the ZendLogWriterMail class; the render function in the PiwikView class; Smarty templates; and the eval function in Smarty.

Unrestricted file upload vulnerability in ofcuploadimage.php in Open Flash Chart v2 Beta 1 through v2 Lug Wyrm Charmer, as used in Piwik 0.2.35 through 0.4.3, Woopra Analytics Plugin before 1.4.3.2, and possibly other products, when registerglobals is enabled, allows remote authenticated users to execute arbitrary code by uploading a file with an executable extension through the name parameter with the code in the HTTPRAWPOSTDATA parameter, then accessing it via a direct request to the file in tmp-upload-images/.

Piwik 0.2.32 and earlier stores sensitive information under the web root with insufficient access control, which allows remote attackers to obtain the API key and other sensitive information via a direct request for misc/cron/archive.sh.
