Depending on the privileges associated with the application, an attacker could install programs view, change, or delete data or create new accounts with full user rights.
APACHE TOMCAT DEFAULT FILES VULNERABILITY CODE
The Apache Tomcat team confirm that all above mentioned tomcat version are vulnerable for dangerous remote code execution (RCE) vulnerability on all operating system if default servlet or WebDAV servlet is enabled with the parameter readonly set to. These files should be removed as they may help an attacker uncover information about the remote Tomcat install or host itself. Successful exploitation of the vulnerability could allow an attacker to read arbitrary files on the affected server. Once file uploaded, the code it contains could be executed by requesting the file. Description : The default error page, default index page, example JSPs, and/or example servlets are installed on the remote Apache Tomcat server. If the server is running a web application that allows for file uploads, a remote file inclusion vulnerability becomes exploitable, that could allow for remote code execution. The example files may also contain vulnerabilities such as cross-site scripting vulnerabilities.' The following default files. Remediation Remove these files from the server. 'Example JSPs and Servlets are installed in the remote Apache Tomcat servlet / JSP container. These files may disclose sensitive information that could help a potential attacker. The vulnerability can be exploited by an attacker who can communicate with the affected AJP protocol service. WEB APPLICATION VULNERABILITIES Standard & Premium Apache Tomcat sample files Description When Apache Tomcat is installed with a default configuration, several example files are also installed. It is important to share port 8009 because it is used by the AJP protocol that contains the vulnerability. A simple way to get it is to run a Docker container from the official Tomcat repository.
Some of these examples are a security risk and should not be deployed on a production server. First of all, I need a system to test the vulnerability. The vulnerability exists in the AJP protocol, which is by default exposed over TCP port 8009 and enabled. WEB APPLICATION VULNERABILITIES Standard & Premium Apache Tomcat examples directory vulnerabilities Description Apache Tomcat default installation contains the '/examples' directory which has many example servlets and JSPs. A vulnerability has been discovered in Apache Tomcat, which could allow for reading of arbitrary files on the affected system.
