Overview<\/strong><\/p>\n

This blog post focuses on the critical vulnerability identified as CVE-2025-32973 that affects XWiki, a popular platform for creating and managing wikis. This vulnerability, found in several versions of the software, can potentially allow attackers to gain programming rights on the affected wiki, leading to serious security implications such as system compromise and data leakage. The severity of this vulnerability and its widespread potential impact on XWiki users<\/a> worldwide makes understanding and mitigating CVE-2025-32973 a priority.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-32973
\nSeverity: Critical (CVSS 9.0)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: System compromise<\/a>, data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

XWiki | 15.9-rc-1 to before 15.10.12
\nXWiki | 16.0.0-rc-1 to before 16.4.3
\nXWiki | 16.5.0-rc-1 to before 16.8.0-rc-1<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability lies in the process<\/a> of editing a document in XWiki. When a user with programming rights edits a document that was last edited by a user without programming rights and contains an XWiki.ComponentClass, there is no warning issued. This allows an attacker to create a malicious<\/a> object which, when edited by an admin user, grants programming rights to the object. For this, the attacker requires edit rights on at least one page to place the object.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Consider the following conceptual example demonstrating how an attacker might exploit<\/a> this vulnerability:<\/p>\n

POST \/XWiki\/editPage HTTP\/1.1\nHost: vulnerable-wiki.example.com\nContent-Type: application\/json\n{\n\"pageId\": \"1234\",\n\"content\": \"\",\n\"lastEditedBy\": \"non-admin-user\"\n}<\/code><\/pre>\n
In this example, an attacker with edit rights to a page sends a POST request to the editPage endpoint, injecting a malicious payload into an XWiki<\/a>.ComponentClass within the content of the page. If this page is subsequently edited by an admin user, the malicious code is executed<\/a>, and the attacker gains programming rights on the wiki.
\nTo prevent this exploit, users are strongly advised to update to the patched versions: 15.10.12, 16.4.3, or 16.8.0-rc-1. If unable, implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) may offer temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
