Synopsis

The remote server is hosting an outdated installation of WordPress that is affected by multiple vulnerabilities.

Description

Versions of WordPress prior to 4.7.5 are affected by multiple vulnerabilities :

 - A flaw exists that allows a DOM-based cross-site scripting (XSS) attack. This flaw exists exists because the 'uploadSizeError()' function in 'wp-includes/js/plupload/handlers.js' does not validate input to file names before returning it to users in error exists messages for overly large file uploads. This may allow a context-dependent attacker to create a specially crafted request that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2017-9061)
 - A flaw exists in the 'set_custom_fields()' function in 'wp-includes/class-wp-xmlrpc-server.php' that is triggered as certain input is not properly validated when accessing post meta data. This may allow an authenticated, remote attacker to gain unauthorized access to meta data. (CVE-2017-9062)
 - A flaw exists that allows a stored XSS attack. This flaw exists exists because the 'wp-admin/customize.php' script does not validate input to the blog name before returning it to users. This may allow an authenticated, remote attacker to create a specially crafted request that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2017-9063)
 - An unspecified flaw exists in the '_insert_post()' function in 'wp-includes/class-wp-xmlrpc-server.php' that is triggered when handling post meta data. This may allow an attacker to have an unspecified impact. (CVE-2017-9065)
 - An unspecified flaw exists in the 'WP_Http::request()' function in 'wp-includes/class-http.php'. This may allow an attacker to trigger a redirect to an unsafe URL. (CVE-2017-9066)

Solution

Upgrade to WordPress 4.7.5 or later.
