Detection Guidance

The vulnerability affects WordPress sites using the Bit SMTP Plugin version 1.2.2 or earlier. Detection involves identifying if your site is running this vulnerable plugin version.

You can check the installed plugin version via the WordPress admin dashboard under Plugins, or by inspecting the plugin files directly.

• grep -r 'Version' wp-content/plugins/bit-smtp/
• cat wp-content/plugins/bit-smtp/readme.txt | grep 'Stable tag'

Additionally, monitoring for unusual authentication attempts or privilege escalation activities in your web server logs may help detect exploitation attempts.
