Executive Summary

CVE-2025-61224 is a reflected Cross-Site Scripting (XSS) vulnerability in DokuWiki's search user interface. It occurs because the namespace selector in the advanced search tools does not properly escape user-supplied input, allowing an attacker to inject malicious scripts. These scripts are then reflected back and executed in the victim's browser without requiring authentication. [1]

Impact Analysis

This vulnerability can allow remote attackers to execute arbitrary scripts in the context of a victim's browser. This can lead to theft of sensitive information, session hijacking, or performing actions on behalf of the user without their consent, potentially compromising user accounts and data. [1]

Detection Guidance

Detection of this vulnerability can be done by testing the search user interface of DokuWiki for reflected Cross-Site Scripting (XSS) via the 'q' parameter or namespace selector in the advanced search tools. You can use tools like curl or a web vulnerability scanner to send crafted requests containing script payloads in the 'q' parameter and observe if the payload is reflected unescaped in the response. For example, a curl command to test might be: curl -v 'http://your-dokuwiki-site/doku.php?q=<script>alert(1)</script>'. If the script tags are reflected unescaped in the response, the vulnerability is present. [1]

Mitigation Strategies

Immediate mitigation steps include updating DokuWiki to a version where this vulnerability is fixed, as reported in the GitHub issue. If an update is not immediately possible, restrict access to the search interface or disable the advanced search tools temporarily to prevent exploitation. Additionally, implement web application firewall (WAF) rules to block requests containing suspicious script payloads in the 'q' parameter or namespace selector inputs. [1]
