Three WooCommerce-API callbacks (payever_set_sandbox_api_keys, payever_toggle_subscription, payever_synchronization_incoming) are registered with no authentication, capability check, or nonce, and the upload_image() routine writes a remotely fetched file to the public uploads directory using an attacker-controlled basename() BEFORE validating the file type. This makes it possible for unauthenticated attackers to write an executable PHP file and achieve remote code execution. NOTE: the token-recovery leg of the full chain depends on the plugin's outbound validateToken() call to Payever's service; the unauthenticated hard-coded-credential identity overwrite (CWE-862/CWE-798) is independently exploitable."}],"title":"payever – WooCommerce Gateway <= 4.8.0 - Unauthenticated Arbitrary File Upload Leading to Remote Code Execution","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/03412063-d73a-4c5c-8dc6-3e76a5d975a5?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/class-payever-synchronization.php?rev=3647773#L22"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/class-payever-synchronization.php?rev=3647773#L116"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/woocommerce-payever-gateway.php?rev=3647773#L145"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/logger/class-payever-logger.php?rev=3647773#L18"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/class-payever-log-manager.php?rev=3647773#L35"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/synchronization/management/class-payever-subscription-manager.php?rev=3647773#L79"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/class-payever-synchronization.php?rev=3647773#L683"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/synchronization/management/class-payever-import-manager.php?rev=3647773#L21"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/synchronization/actions/class-payever-action-update-product.php?rev=3647773#L448"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/includes/synchronization/actions/class-payever-action-update-product.php?rev=3647773#L547"},{"url":"https://plugins.trac.wordpress.org/browser/payever-woocommerce-gateway/trunk/vendor/payever/core-sdk-php/lib/Payever/Core/Http/Client/CurlClient.php?rev=3647773#L258"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3761918%40payever-woocommerce-gateway&new=3761918%40payever-woocommerce-gateway"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-434 Unrestricted Upload of File with Dangerous Type","cweId":"CWE-434","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"Supakiad S.
