Apache tomcat 7.0 275/1/2023 It is likely that users upgrading to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations. A number of changes were made to the default AJP Connector configuration in 9.0.31 to harden the default configuration. Users wishing to take a defence-in-depth approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. It is important to note that mitigation is only required if an AJP port is accessible to untrusted users. My expectation is that 6.x and 5.x would be vulnerable to CVE-2017-12617 as well as CVE-2017-12615 and CVE-2017-12616 in some form as the code that handles resources in 7.0.x is also present (in an early form) in those. I haven't tested them and I don't plan to test them. This vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the web application - processing any file in the web application as a JSP Further, if the web application allowed file upload and stored those files within the web application (or the attacker was able to control the content of the web application by some other means) then this, along with the ability to process a file as a JSP, made remote code execution possible.

It was expected (and recommended in the security guide) that this Connector would be disabled if not required. Free apache tomcat 7.0.27 download software at UpdateStar - Apache Tomcat is a web server that is an open source software implementation of the Java Servlet and JavaServer Pages technologies. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. If such connections are available to an attacker, they can be exploited in ways that may be surprising. Removed 7.0.78-1 from unstable (Debian FTP Masters). Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. Accepted tomcat7 7.0.56-3+really7.0.100-1+deb8u1 (source all) into. (markt) Update the copy of Apache Commons DBCP 1.4.x and Apache Commons pool 1.5.x to the latest source code as of to pick up multiple bug fixes including 58338. When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. Copy Apache Commons DBCP 1.4 and Apache Commons Pool 1.5.7 source code into the Tomcat 7.0.x tree to enable additional fixes to be pulled in. A successful attack can lead to local file inclusion. This signature detects attempts to exploit a known vulnerability against Apache Tomcat. Apache Tomcat AJP Connector Local File Inclusion
