What is Ghostcat Vulnerability?

Ghostcat is a vulnerability that affects Apache Tomcat. It is caused by an insecure configuration of the AJP protocol in the default installation of Tomcat, leading to attackers being able to read or include any files in the webapp directories of Tomcat and giving them the advantage of remote code execution.

What is AJP?

AJP stands for Apache Jserv Protocol, and it is used as an optimized version of the HTTP protocol in binary form. By default, AJP is enabled in Apache Tomcat, and is set to listen on port 8009.

What versions of the Tomcat are affected?

Apache Tomcat 9.x < 9.0.31, Apache Tomcat 8.x < 8.5.51, Apache Tomcat 7.x < 7.0.100, Apache Tomcat 6.x

We check for:

The accessibility of port 8009
