Product: User Login History Wordpress Plugin - https://wordpress.org/plugins/user-login-history/ Vendor: Er Faiyaz Alam Tested version: 1.5.2 CVE ID: CVE-2017-15867 ** CVE description ** Multiple cross-site scripting (XSS) vulnerabilities in the user-login-history plugin through 1.5.2 for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) date_from, (2) date_to, (3) user_id, (4) username, (5) country_name, (6) browser, (7) operating_system, or (8) ip_address parameter to admin/partials/listing/listing.php. ** Technical details ** The above-mentioned HTTP GET parameters are directly put into the value attribute of an HTML form field without proper sanitization.
