How the Exploit Works

With the CVE-2025-24853 vulnerability, attackers can create a request using a carefully crafted header link with wiki markup syntax. This request can then be utilized to execute javascript in the victim’s browser. This exploit could potentially allow attackers to retrieve sensitive data from the victim’s system.

Conceptual Example Code

The following example demonstrates a conceptual exploit of this vulnerability:

POST /jspwiki/wikimarkup HTTP/1.1
Host: target.example.com
Content-Type: text/plain
[[_header text_|javascript:alert(document.cookie)]]

In this example, an attacker might craft a POST request that includes a malicious header link in the wiki markup syntax. The link contains a javascript code that, when executed, would display the victim’s cookies, potentially revealing sensitive information.

Mitigation Guidance

Users are advised to upgrade to Apache JSPWiki 2.12.3 or later versions to mitigate the risk of this vulnerability. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and block attempts to exploit this vulnerability.
