WordPress Privilege Escalation Vulnerability

CVE-2018-12895

WordPress through 4.9.6 allows Author users to execute arbitrary code by leveraging directory traversal in the wp-admin/post.php thumb parameter, which is passed to the PHP unlink function and can delete the wp-config.php file. This is related to missing filename validation in the wp-includes/post.php wp_delete_attachment function. The attacker must have capabilities for files and posts that are normally available only to the Author, Editor, and Administrator roles. The attack methodology is to delete wp-config.php and then launch a new installation process to increase the attacker's privileges.

CVE-2018-1000556

WordPress version 4.8 + contains a Cross Site Scripting (XSS) vulnerability in plugins.php or core wordpress on delete function that can result in an attacker performing client-side attacks which could range from stealing a cookie to code injection. This attack appears to be exploitable via an attacker crafting an URL with payload and sending to the user. Victim need to open the link to be affected by reflected XSS.

 

PHP Denial of Service Vulnerability

CVE-2018-12882

exif_read_from_impl in ext/exif/exif.c in PHP 7.2.x through 7.2.7 allows attackers to trigger a use-after-free (in exif_read_from_file) because it closes a stream that it is not responsible for closing. The vulnerable code is reachable through the PHP exif_read_data function.
