Background
The jspwiki-war package is an Apache JSPWiki web application that provides a collaborative platform for creating and editing content. It is built using the Maven ecosystem. The package allows users to create and manage wiki pages, with features such as version control, access control, and plugins. However, versions up to 2.10.5 of jspwiki-war are vulnerable to a cross-site scripting (XSS) attack.
Vulnerability Detail
The vulnerability in jspwiki-war allows an attacker to execute arbitrary JavaScript code in the context of a victim's browser. By crafting a malicious URL, an attacker can inject and execute malicious scripts, potentially leading to session hijacking. This can result in unauthorized access to sensitive information or the manipulation of user sessions. The vulnerability has a CVSS score of 6.1, indicating a moderate severity level.

Workaround
If upgrading to the latest version is not immediately feasible, a temporary workaround is to sanitize user input before displaying it in the application. Implement input validation and output encoding to prevent the execution of malicious scripts. Here is an example of how to sanitize user input in Java:
import org.apache.commons.lang.StringEscapeUtils;
public class Sanitizer {
public static String sanitize(String input) {
return StringEscapeUtils.escapeHtml(input);
}
}
Conclusion
The jspwiki-war package, up to version 2.10.5, is vulnerable to a cross-site scripting (XSS) attack. This can lead to session hijacking and unauthorized access to sensitive information. To fix this vulnerability, it is recommended to upgrade to version 2.11.0.M1 or later. If immediate upgrading is not possible, implement input validation and output encoding to sanitize user input.
