DescriptionGitHub Advisory

XWiki is a generic wiki platform. In versions before 15.10.16, 16.0.0-rc-1 through 16.4.6, and 16.5.0-rc-1 through 16.10.1, when an attacker without script or programming right creates an XClass definition in XWiki (requires edit right), and that same document is later edited by a user with script, admin, or programming right, malicious code could be executed with the rights of the editing user without prior warning. In particular, this concerns custom display code, the script of computed properties and queries in database list properties. Note that warnings before editing documents with dangerous properties have only been introduced in XWiki 15.9, before that version, this was a known issue and the advice was simply to be careful. This has been patched in XWiki 16.10.2, 16.4.7 and 15.10.16 by adding an analysis for the respective XClass properties.

Executive ViewAI

Why It Matters

XWiki instances are vulnerable to privilege escalation attacks where users with basic edit rights can inject malicious code that executes with elevated privileges when edited by administrators or privileged users. This affects multiple XWiki versions and requires immediate patching to prevent unauthorized system compromise.

Business Impact: High

Compensating Controls

Apply vendor patch. If patching cannot be completed immediately: (1) Restrict XClass creation to privileged users only via access controls, (2) Enable and monitor document edit audit logs for changes to XClass definitions, (3) Implement code review process requiring approval before privileged users edit documents with custom XClass properties, (4) Consider disabling custom XClass properties and computed properties features if not essential to operations.

Attack Technique

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
