Lifecycle Timeline
2DescriptionCVE.org
The Woosa - Marktplaats for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Read via Path Traversal in versions up to and including 2.0.4. This is due to insufficient path sanitization in the render_logs_ui() function, which accepts a base64-encoded file name from the 'log_file' GET parameter and concatenates it directly with the plugin's log directory path without validating that the resolved path remains within the intended directory. This makes it possible for authenticated attackers, with Administrator-level access, to read the contents of arbitrary files on the server, including wp-config.
AnalysisAI
Arbitrary file read via path traversal in the Woosa - Marktplaats for WooCommerce WordPress plugin (versions up to and including 2.0.4) permits authenticated WordPress administrators to escape the plugin's log directory and access any file readable by the web server process, including the sensitive wp-config.php file. The flaw exists in the render_logs_ui() function within class-module-logger-hook-settings.php, which decodes a base64-supplied filename from the log_file GET parameter and concatenates it with the log directory path without any boundary enforcement. No public exploit code or active exploitation has been identified at time of analysis; the attack surface is meaningfully constrained by the Administrator-level privilege requirement (PR:H), though successful exploitation could cascade into full site compromise via exposed database credentials.
Technical ContextAI
The vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory - 'Path Traversal'), occurring in the vendor-bundled Woosa logger library at class-module-logger-hook-settings.php (lines 177 and 190). The affected plugin (CPE: cpe:2.3:a:teamwsa:woosa_-_marktplaats_for_woocommerce) is a WooCommerce integration for the Dutch Marktplaats marketplace. The root cause is a classic unsanitized concatenation pattern: the render_logs_ui() function accepts a base64-encoded filename from the log_file GET parameter, decodes it, and appends it directly to the plugin's designated log directory path. Because PHP's file-reading functions will resolve directory traversal sequences (e.g., ../../) after this concatenation, an attacker can escape the log directory entirely. Base64 encoding serves only as obfuscation, not a security boundary. The WordPress plugin architecture means this endpoint is exposed via the admin dashboard, restricting access to authenticated administrator sessions. The affected code exists in a shared logger library under the vendor/ directory, suggesting the flaw may appear in other Woosa-branded plugins using the same library.
RemediationAI
Vendor-released patch: version 2.0.5. Site administrators should update the Woosa - Marktplaats for WooCommerce plugin to version 2.0.5 immediately via the WordPress admin dashboard (Plugins → Updates) or via WP-CLI (wp plugin update integration-marktplaats-for-woocommerce). The fix is confirmed in the plugin's trac changeset at https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3576889%40integration-marktplaats-for-woocommerce&new=3576889%40integration-marktplaats-for-woocommerce, and the patched source is visible at https://plugins.trac.wordpress.org/browser/integration-marktplaats-for-woocommerce/tags/2.0.5/vendor/woosa/logger/class-module-logger-hook-settings.php. If immediate patching is not possible, a compensating control is to restrict access to the WordPress admin area by IP allowlist at the web server or WAF layer - note this does not eliminate the vulnerability but blocks unauthenticated and non-whitelisted access paths. Additionally, review WordPress administrator accounts for any unauthorized additions, as this vulnerability is only exploitable by already-privileged users.
