Background
Apache Tomcat is an open-source web server and servlet container that is widely used for hosting Java-based web applications. It provides a Java Servlet and JavaServer Pages (JSP) environment for running web applications. The calendar examples application in Apache Tomcat 4.1.31 is vulnerable to cross-site request forgery (CSRF) attacks. This vulnerability allows remote attackers to add events as arbitrary users by exploiting the time and description parameters in the cal2.jsp file.
Vulnerability Detail
The CSRF vulnerability in cal2.jsp allows an attacker to trick authenticated users into performing unwanted actions on behalf of the attacker. By crafting a malicious request and tricking a user into visiting a specially crafted webpage, the attacker can add events to the calendar examples application as if they were the authenticated user. This can lead to unauthorized access, data manipulation, and potential security breaches. Additionally, the application is also susceptible to cross-site scripting (XSS) attacks, which can allow an attacker to inject malicious scripts into the application and potentially steal sensitive information or perform other malicious actions.
How To Fix
No fixed version is published for this vulnerability.

Workaround
A possible workaround for the CSRF vulnerability is to disable the calendar examples application if it is not needed. This can be done by removing or disabling the corresponding web application file. However, this workaround may not be suitable if the application is required for functionality. For the XSS vulnerability, input validation and output encoding should be implemented to sanitize user input and prevent script injection.
Conclusion
The Apache Tomcat calendar examples application in version 4.1.31 is vulnerable to CSRF and XSS attacks. It is important to apply the recommended fixes and security measures to protect against these vulnerabilities.

FAQ
Apache Tomcat is an open-source web server and servlet container that is widely used for hosting Java-based web applications.
Cross-site request forgery (CSRF) is a type of attack that tricks authenticated users into performing unwanted actions on behalf of the attacker.
Cross-site scripting (XSS) is a type of vulnerability that allows attackers to inject malicious scripts into web applications, potentially leading to data theft or other malicious actions.
To fix the CSRF vulnerability, it is recommended to implement proper CSRF protection mechanisms such as using anti-CSRF tokens, checking the Referer header, or implementing the SameSite attribute for cookies.
To prevent XSS attacks, input validation and output encoding should be implemented to sanitize user input and prevent script injection.
