CVE-2025-30220: GeoTools, GeoServer, and GeoNetwork XML External Entity (XXE) Processing Vulnerability in XSD schema handling

Noroxi assessment

Priority: Plan (action score 49/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 43.6% (FIRST EPSS); higher than 98.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: org.geonetwork-opensource:gn-web-app (Maven) 4.2.13, 4.4.8; org.geonetwork-opensource:gn-wfsfeature-harvester (Maven) 4.2.13, 4.4.8; org.geoserver:gs-wfs (Maven) 2.26.3, 2.27.1, 2.25.7.

Add it to your regular patch cycle. Upgrade to org.geonetwork-opensource:gn-web-app (Maven) 4.2.13, 4.4.8; org.geonetwork-opensource:gn-wfsfeature-harvester (Maven) 4.2.13, 4.4.8; org.geoserver:gs-wfs (Maven) 2.26.3, 2.27.1, 2.25.7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

GeoServer is an open source server that allows users to share and edit geospatial data. GeoTools Schema class use of Eclipse XSD library to represent schema data structure is vulnerable to XML External Entity (XXE) exploit. This impacts whoever exposes XML processing with gt-xsd-core involved in parsing, when the documents carry a reference to an external XML schema. The gt-xsd-core Schemas class is not using the EntityResolver provided by the ParserHandler (if any was configured). This also impacts users of gt-wfs-ng DataStore where the ENTITY_RESOLVER connection parameter was not being used as intended. This vulnerability is fixed in GeoTools 33.1, 32.3, 31.7, and 28.6.1, GeoServer 2.27.1, 2.26.3, and 2.25.7, and GeoNetwork 4.4.8 and 4.2.13.
