Background
Apache Tomcat is an open-source web server and servlet container that is used to deploy Java web applications. It provides a Java HTTP web server environment for running Java code. The CookieExample servlet in Apache Tomcat versions 3.3 through 3.3.2 is vulnerable to cross-site scripting (XSS) attacks. This vulnerability allows remote attackers to inject arbitrary web script or HTML into the application.
Vulnerability Detail
The vulnerability exists in the examples/servlet/CookieExample servlet of Apache Tomcat. It is caused by improper input validation of the Name and Value fields, which are used to set cookies. An attacker can exploit this vulnerability by injecting malicious script or HTML code into these fields. When the application processes the input, the injected code is executed in the context of the user's browser, leading to potential XSS attacks. This can result in the theft of sensitive information, session hijacking, or the execution of arbitrary code.
How To Fix
No fixed version is published for this vulnerability.

Workaround
If upgrading to a newer version of Apache Tomcat is not immediately possible, a temporary workaround is to disable or restrict access to the examples/servlet/CookieExample servlet. This can be done by modifying the server configuration or deploying a custom security filter that blocks access to the vulnerable servlet.
Conclusion
In conclusion, Apache Tomcat's CookieExample servlet is vulnerable to cross-site scripting (XSS) attacks. This vulnerability can be exploited by injecting malicious script or HTML code into the Name and Value fields used to set cookies. Upgrading to a non-affected version of Apache Tomcat is the recommended solution. If immediate upgrade is not possible, restricting access to the vulnerable servlet can serve as a temporary workaround. For further support on vulnerability remediation, please contact DevNack.com.
