Synopsis

WordPress 4.7.x < 4.7.8 Multiple Vulnerabilities

Description

According to its self-reported version number, the detected WordPress application is affected by multiple vulnerabilities :

 - wp-admin/user-new.php sets the newbloguser key to a string that can be directly derived from the user ID, which allows remote attackers to bypass intended access restrictions by entering this string.

 - wp-includes/functions.php does not require the unfiltered_html capability for upload of .js files, which might allow remote attackers to conduct XSS attacks via a crafted file.

 - wp-includes/general-template.php does not properly restrict the lang attribute of an HTML element, which might allow attackers to conduct XSS attacks via the language setting of a site.

 - wp-includes/feed.php does not properly restrict enclosures in RSS and Atom fields, which might allow attackers to conduct XSS attacks via a crafted URL.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to WordPress version 4.7.8 or latest.
