CVE-2024-36404: GeoServer and GeoTools - Remote Code Execution

id: CVE-2024-36404

info:
  name: GeoServer and GeoTools - Remote Code Execution
  author: ritikchaddha,darses
  severity: critical
  description: |
    GeoTools is an open source Java library that provides tools for geospatial data. Prior to versions 31.2, 30.4, and 29.6, Remote Code Execution (RCE) is possible if an application uses certain GeoTools functionality to evaluate XPath expressions supplied by user input. Versions 31.2, 30.4, and 29.6 contain a fix for this issue. As a workaround, GeoTools can operate with reduced functionality by removing the `gt-complex` jar from one's application. As an example of the impact, application schema `datastore` would not function without the ability to use XPath expressions to query complex content. Alternatively, one may utilize a drop-in replacement GeoTools jar from SourceForge for versions 31.1, 30.3, 30.2, 29.2, 28.2, 27.5, 27.4, 26.7, 26.4, 25.2, and 24.0. These jars are for download only and are not available from maven central, intended to quickly provide a fix to affected applications.
