Synopsis
A PHP application running on the remote web server is affected by multiple vulnerabilities.Description
According to its self-reported version number, the WordPress application running on the remote web server is prior to 4.7.3.It is, therefore, 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.
- A directory traversal vulnerability exists in WordPress' wp-json component due to an error in post listing. An unauthenticated, remote attacker can exploit this, by sending a URI that contains directory traversal characters, to disclose the contents of files located outside of the server's restricted path.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
