Description
The WP Encryption – One Click Free SSL Certificate & SSL / HTTPS Redirect, Security & SSL Scan plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 7.8.6.6 via the 'imploded' parameter parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. Although file write content is passed through esc_html(), which encodes angle brackets and prevents direct PHP execution, plaintext configuration files such as .htaccess are fully writable and exploitable for denial-of-service or redirect attacks. This is only exploitable when the premium version of the software is enabled and active.
