SynopsisA PHP application running on the remote web server is affected by multiple vulnerabilities.
DescriptionAccording to its self-reported version number, the WordPress application running on the remote web server is prior to 4.7.2.
It is, therefore, affected by multiple vulnerabilities :
- An information disclosure vulnerability exists in the class-wp-press-this.php script due to a failure to properly restrict the user interface for assigning taxonomy terms. An authenticated, remote attacker can exploit this to disclose sensitive information.
- A SQL injection (SQLi) vulnerability exists in the class-wp-query.php script due to a failure to sanitize input to post type names. An unauthenticated, remote attacker can exploit this to inject or manipulate SQL queries in the back-end database, resulting in the disclosure or manipulation of arbitrary data.
- A cross-site scripting (XSS) vulnerability exists in the class-wp-posts-list-table.php script due to improper validation of input to the posts list table. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-5612)
- A privilege escalation vulnerability exists in the REST API due to a failure to properly sanitize user-supplied input to the 'id' parameter when editing or deleting blog posts. An unauthenticated, remote attacker can exploit this issue to run arbitrary PHP code, inject content into blog posts, modify blog post attributes, or delete blog posts. (CVE-2017-1001000)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
