Ghostcat is a serious vulnerability in Apache Tomcat. Due to a flaw in the Tomcat AJP protocol, an attacker can read or include any files in the webapp directories of Tomcat. For example: an attacker can read the webapp configuration files or source code.
In addition, if the website application allows users to upload files, an attacker can first upload a file (any file type) containing malicious JSP script code to the server, and then include the uploaded file by exploiting the Ghostcat vulnerability, which can then be used for remote code execution.
