Description
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.
Understanding This Vulnerability
This Common Vulnerabilities and Exposures (CVE) entry provides detailed information about a security vulnerability that has been publicly disclosed. CVEs are standardized identifiers assigned by MITRE Corporation to track and catalog security vulnerabilities across software and hardware products.
The severity rating (None) indicates the potential impact of this vulnerability based on the CVSS (Common Vulnerability Scoring System) framework. Higher severity ratings typically indicate vulnerabilities that could lead to more significant security breaches if exploited. Security teams should prioritize remediation efforts based on severity, exploit availability, and the EPSS (Exploit Prediction Scoring System) score, which predicts the likelihood of exploitation in the wild.
If this vulnerability affects products or systems in your infrastructure, we recommend reviewing the affected products section, checking for available patches or updates from vendors, and implementing recommended workarounds or solutions until a permanent fix is available. Organizations should also monitor security advisories and threat intelligence feeds for updates about active exploitation of this vulnerability.
