CVE-2020-8658
The BestWebSoft Htaccess plugin through 1.8.1 for WordPress allows wp-admin/admin.php?page=htaccess.php&action=htaccess_editor CSRF.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The BestWebSoft Htaccess plugin through 1.8.1 for WordPress allows wp-admin/admin.php?page=htaccess.php&action=htaccess_editor CSRF. The flag htccss_nonce_name passes the nonce to WordPress but the plugin does not validate it correctly, resulting in a wrong implementation of anti-CSRF protection. In this way, an attacker is able to direct the victim to a malicious web page that modifies the .htaccess file, and takes control of the website.
