Wordpress : Security Vulnerabilities, CVEs, CVSS score between 7 and 7.99

WordPress 2.0.6, and 2.1Alpha 3 (SVN:4662), does not properly verify that the m parameter value has the string data type, which allows remote attackers to obtain sensitive information via an invalid m[] parameter, as demonstrated by obtaining the path, and obtaining certain SQL information such as the table prefix.

The wp_remote_fopen function in WordPress before 2.1 allows remote attackers to cause a denial of service (bandwidth or thread consumption) via pingback service calls with a source URI that corresponds to a large file, which triggers a long download session without a timeout constraint.

WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. ### Impact The issue allows an authenticated but low-privileged user (like contributor/author) to execute XSS in the editor. This bypasses the restrictions imposed on users who do not have the permission to post `unfiltered_html`. ### Patches This has been patched in WordPress 5.8, and will be pushed to older versions via minor releases (automatic updates). It's strongly recommended that you keep auto-updates enabled to receive the fix. ### References https://wordpress.org/news/category/releases/ https://hackerone.com/reports/1142140 ### For more information If you have any questions or comments about this advisory: * Open an issue in [HackerOne](https://hackerone.com/wordpress)

WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. In affected versions the widgets editor introduced in WordPress 5.8 beta 1 has improper handling of HTML input in the Custom HTML feature. This leads to stored XSS in the custom HTML widget. This has been patched in WordPress 5.8. It was only present during the testing/beta phase of WordPress 5.8.

WordPress is an open publishing platform for the Web. It's possible for a file of a type other than a zip file to be submitted as a new plugin by an administrative user on the Plugins -> Add New -> Upload Plugin screen in WordPress. If FTP credentials are requested for installation (in order to move the file into place outside of the `uploads` directory) then the uploaded file remains temporary available in the Media Library despite it not being allowed. If the `DISALLOW_FILE_EDIT` constant is set to `true` on the site _and_ FTP credentials are required when uploading a new theme or plugin, then this technically allows an RCE when the user would otherwise have no means of executing arbitrary PHP code. This issue _only_ affects Administrator level users on single site installations, and Super Admin level users on Multisite installations where it's otherwise expected that the user does not have permission to upload or execute arbitrary PHP code. Lower level users are not affected. Sites where the `DISALLOW_FILE_MODS` constant is set to `true` are not affected. Sites where an administrative user either does not need to enter FTP credentials or they have access to the valid FTP credentials, are not affected. The issue was fixed in WordPress 6.4.3 on January 30, 2024 and backported to versions 6.3.3, 6.2.4, 6.1.5, 6.0.7, 5.9.9, 5.8.9, 5.7.11, 5.6.13, 5.5.14, 5.4.15, 5.3.17, 5.2.20, 5.1.18, 5.0.21, 4.9.25, 2.8.24, 4.7.28, 4.6.28, 4.5.31, 4.4.32, 4.3.33, 4.2.37, and 4.1.40. A workaround is available. If the `DISALLOW_FILE_MODS` constant is defined as `true` then it will not be possible for any user to upload a plugin and therefore this issue will not be exploitable.

SQL injection vulnerability in log.header.php in WordPress 0.7 and earlier allows remote attackers to execute arbitrary SQL commands via the posts variable.

PHP remote file inclusion vulnerability in wp-links/links.all.php in WordPress 0.70 allows remote attackers to execute arbitrary PHP code via a URL in the $abspath variable.

SQL injection vulnerability in wp-trackback.php in Wordpress 1.5 and earlier allows remote attackers to execute arbitrary SQL commands via the tb_id parameter.

SQL injection vulnerability in template-functions-category.php in WordPress 1.5.1 allows remote attackers to execute arbitrary SQL commands via the $cat_ID variable, as demonstrated using the cat parameter to index.php.

SQL injection vulnerability in XMLRPC server in WordPress 1.5.1.2 and earlier allows remote attackers to execute arbitrary SQL commands via input that is not filtered in the HTTP_RAW_POST_DATA variable, which stores the data in an XML file.

Direct code injection vulnerability in WordPress 1.5.1.3 and earlier allows remote attackers to execute arbitrary PHP code via the cache_lastpostdate[server] cookie.

SQL injection vulnerability in WordPress 1.5.2, and possibly other versions before 2.0, allows remote attackers to execute arbitrary SQL commands via the User-Agent field in an HTTP header for a comment.

Direct static code injection vulnerability in WordPress 2.0.2 and earlier allows remote attackers to execute arbitrary commands by inserting a carriage return and PHP code when updating a profile, which is appended after a special comment sequence into files in (1) wp-content/cache/userlogins/ (2) wp-content/cache/users/ which are later included by cache.php, as demonstrated using the displayname argument.

wp-trackback.php in WordPress 2.0.6 and earlier does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary SQL commands via the tb_id parameter. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in WordPress.

WordPress 2.1.1, as downloaded from some official distribution sites during February and March 2007, contains an externally introduced backdoor that allows remote attackers to execute arbitrary commands via (1) an eval injection vulnerability in the ix parameter to wp-includes/feed.php, and (2) an untrusted passthru call in the iz parameter to wp-includes/theme.php.

SQL injection vulnerability in wp-admin/admin-ajax.php in WordPress before 2.2 allows remote attackers to execute arbitrary SQL commands via the cookie parameter.

Multiple SQL injection vulnerabilities in Wordpress before 2.2.3 and Wordpress multi-user (MU) before 1.2.5a allow remote attackers to execute arbitrary SQL commands via the post_type parameter to the pingback.extensions.getPingbacks method in the XMLRPC interface, and other unspecified parameters related to "early database escaping" and missing validation of "query string like parameters."

Directory traversal vulnerability in wp-db-backup.php in WordPress 2.0.3 and earlier allows remote attackers to read arbitrary files, delete arbitrary files, and cause a denial of service via a .. (dot dot) in the backup parameter in a wp-db-backup.php action to wp-admin/edit.php. NOTE: this might be the same as CVE-2006-5705.1.

Unrestricted file upload vulnerability in ajaxfilemanager.php in the Wp-FileManager 1.2 plugin for WordPress allows remote attackers to upload and execute arbitrary PHP code via unspecified vectors.

SQL injection vulnerability in functions/editevent.php in the WP-Cal 0.3 plugin for WordPress allows remote attackers to execute arbitrary SQL commands via the id parameter.

Multiple SQL injection vulnerabilities in main.php in the WassUp plugin 1.4 through 1.4.3 for WordPress allow remote attackers to execute arbitrary SQL commands via the (1) from_date or (2) to_date parameter to spy.php.

SQL injection vulnerability in wordspew-rss.php in the Wordspew plugin before 3.72 for Wordpress allows remote attackers to execute arbitrary SQL commands via the id parameter.

SQL injection vulnerability in shiftthis-preview.php in the ShiftThis Newsletter (st_newsletter) plugin for WordPress allows remote attackers to execute arbitrary SQL commands via the newsletter parameter.
