| Detailed Description |
A version of WordPress software which is older than version 4.7.3 is detected as installed on the host. WordPress is a freely available PHP-based publication program that uses a MySQL backend database. WordPress versions 4.7.x prior to 4.7.3 are affected by multiple vulnerabilities :
- A cross-site scripting (XSS) vulnerability exists in the wp_playlist_shortcode() function within the /wp-includes/media.php script due to a failure to validate input passed via audio file metadata before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.
- A cross-site redirection vulnerability exists due to a failure to validate input passed via control characters before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted link, to redirect a user from an intended legitimate website to an arbitrary website of the attacker's choosing.
- An unspecified flaw exists in the plugin deletion functionality that allows an authenticated, remote attacker to delete unintended files.
- A cross-site scripting (XSS) vulnerability exists due to a failure to validate input to video URLs in YouTube embeds before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.
- A cross-site scripting (XSS) vulnerability exists due to a failure to validate input to taxonomy term names before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.
- A cross-site request forgery (XSRF) vulnerability exists in the Press This functionality, specifically within /wp-admin/press-this.php when handling HTTP requests, due to a failure to require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. An unauthenticated, remote attacker can exploit this, by convincing a user to follow a specially crafted link, to cause excessive consumption of server resources.
- A DOM-based cross-site scripting (XSS) vulnerability exists in the renderTracks() function within the /wp-includes/js/mediaelement/wp-playlist.min.js script due to a failure to validate input passed via audio file metadata before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.
* Note: This check solely relied on the version number of the WordPress software installed on the remote Web server to assess this vulnerability, so this might be a false positive.
