Detailsinfo

A vulnerability was found in Dynamic XWiki up to 17.3.0. It has been declared as problematic. This vulnerability affects some unknown functionality of the component Administration Interface. The manipulation of the argument Meta Info with an unknown input leads to a improper neutralization of special elements used in a template engine vulnerability. The CWE definition for the vulnerability is CWE-1336. The product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

XWiki through version 17.3.0 is vulnerable to Server-Side Template Injection (SSTI) in the Administration interface, specifically within the HTTP Meta Info field of the Global Preferences Presentation section. An authenticated administrator can inject crafted Apache Velocity template code, which is rendered on the server side without proper validation or sandboxing. This enables the execution of arbitrary template logic, which may expose internal server information or, in specific configurations, lead to further exploitation such as remote code execution or sensitive data leakage. The vulnerability resides in improper handling of dynamic template rendering within user-supplied configuration fields.

This vulnerability was named CVE-2025-51991 since 06/16/2025. The exploitation appears to be easy. The attack can be initiated remotely. Additional levels of successful authentication are required for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1221.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
