Report a false positive

Rule Category

SERVER-WEBAPP -- Snort has detected traffic exploiting vulnerabilities in web based applications on servers.

Alert Message

SERVER-WEBAPP WordPress Plugin ThemeREX PHP code injection attempt

Rule Explanation

The vulnerable source code should no longer be present in the Wordpress plugins after applying a fix, thus if the rule alerts then there is a high chance that someone is trying to exploit this vulnerability. This rule will search for the vulnerable parameter in the ThemeRex plugin and will drop any packets containing it.

What To Look For

This rule will trigger when an attempt of accessing a vulnerable REST-API endpoint using a ThemeREX Add-on plugin of Wordpress, is detected. Accessing this vulnerable resource will cause a code injection vulnerability and the whole Wordpress system will be affected.
