![]() ![]() ![]() If such connections are available to an attacker, they can be exploited in ways that may be surprising. For example, you can use %i in the log format string of the origin server to log the original clients IP address, but you may get more than one address if the request passes through several proxies. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. X-Forwarded-Server: The hostname of the proxy server.Ä«e careful when using these headers on the origin server, since they will contain more than one (comma-separated) value if the original request already contained one of these headers.X-Forwarded-Host: The original host requested by the client in the Host HTTP request header.Tomcat treats AJP connections as having higher trust than, for example, a. Long story short, in Tomcat 9.0.31 (and onward), the AJP connector is not going to be enabled by default. When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. I must say, though, that this is just a blog about Olafs efforts, Im now just playing Watson to his Holmes. The intent of this project is to help you 'Learn Java by Example' TM. 3 Answers Sorted by: 23 Do it like this: in the apache config: ProxyPass ajp://localhost:8009/foo ProxyPassReverse ajp://localhost:8009/foo And then in your server.xml:![]() X-Forwarded-For: The IP address of the client. 4.1 Installing Connector/J from a Binary Distribution 4.2 Installing Connector/J Using Maven 4.3 Installing from Source 4.4 Upgrading from an Older Version 4.4.1 Upgrading to MySQL Connector/J 8.1 4.5 Testing Connector/J 5 Connector/J Examples 6 Connector/J Reference 6.1 Driver/Datasource Class Name 6.2 Connection URL Syntax 6.3 Configuration. Since Im a big fan of using AJP to connect Apache HTTPd and Tomcat, I thought Id share what he found with you. Tomcat example source code file (ajp.xml) This example Tomcat source code file (ajp.xml) is included in the 'Java Source Code Warehouse' project.This connection is treated with more trust than a connection such as HTTP, allowing an. Apache Tomcat includes the AJP connector, which is enabled by default and listens on all addresses on port 8009. When acting in a reverse-proxy mode (using the ProxyPass directive, for example), mod_proxy_http adds several request headers in order to pass information to the origin server. Ghostcat is a vulnerability found in Apache Tomcat versions 6.x, 7.x, 8.x, and 9.x that allows remote code execution in some circumstances. You can read the X-Forwarded-For in the request header. ![]()
