CVE-2020-1745 is a file read/inclusion using the AJP connector in Undertow and very similar to CVE-2020-1938.In instances where a poorly configured server allows file uploads, an attacker could upload malicious JavaServer Pages (JSP) code within a variety of file types to gain remote code execution (RCE) A remote, unauthenticated/untrusted attacker could exploit this AJP configuration to read web application files from a server exposing the AJP port to untrusted clients. The AJP protocol is enabled by default, with the AJP connector listening in TCP port 8009 and bond to IP address 0.0.0.0. CVE-2020-1938 is a file read/inclusion using the AJP connector in Apache Tomcat.Vulnerabilities "CVE-2020-1938" and "CVE-2020-1745" have been reported in April 2020 for the Apache Tomcat AJP connector to suffer from a "Request Injection" (Ghostcat) type of attack, namely: Can anyone tell me what/where Ive gone wrong. However I now wish to enable SSL and when I create the vhost section for SSL and try access my application over SSL the tomcat section of my application doesnt work. Im using AJP connector (modproxy) to do this. In DDOS and DDMC versions in which the AJP connector is configured to listen only on localhost, there is no risk, as there is no way an attacker can leverage any problems in AJP, unless if the attacker has already broken into DDOS / DDMC, in which case, the attacker would already be in full control of the server. I have tomcat running behind Apache for the last 2 years and everything is going well. The mentioned AJP connector doesn't really need to be open for the network as a whole, as the only communication taking place is between the Apache frontend and the Tomcat backend, which are running both on the same host. There is an application server (Tomcat) at the backend, talking with the fronted via the AJP connector, and running the graphical interface, replying to the frontend with the HTML / JS to send to the customer browser for rendering.There is a web server (Apache) at the fronted taking up the browser's requests and establishing SSL connections when requested.Both DDOS and DDMC have the same architecture for their respective GUI:
