CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

GeoServer is an open source server that allows users to share and edit geospatial data. Prior to versions 2.22.6, 2.23.6, 2.24.4, and 2.25.2, multiple OGC request parameters allow Remote Code Execution (RCE) by unauthenticated users through specially crafted input against a default GeoServer installation due to unsafely evaluating property names as XPath expressions. The GeoTools library API that GeoServer calls evaluates property/attribute names for feature types in a way that unsafely passes them to the commons-jxpath library which can execute arbitrary code when evaluating XPath expressions. This XPath evaluation is intended to be used only by complex feature types (i.e., Application Schema data stores) but is incorrectly being applied to simple feature types as well which makes this vulnerability apply to **ALL** GeoServer instances. No public PoC is provided but this vulnerability has been confirmed to be exploitable through WFS GetFeature, WFS GetPropertyValue, WMS GetMap, WMS GetFeatureInfo, WMS GetLegendGraphic and WPS Execute requests. This vulnerability can lead to executing arbitrary code. Versions 2.22.6, 2.23.6, 2.24.4, and 2.25.2 contain a patch for the issue. A workaround exists by removing the `gt-complex-x.y.jar` file from the GeoServer where `x.y` is the GeoTools version (e.g., `gt-complex-31.1.jar` if running GeoServer 2.25.1). This will remove the vulnerable code from GeoServer but may break some GeoServer functionality or prevent GeoServer from deploying if the gt-complex module is needed.

    OSGeo GeoServer GeoTools Eval Injection Vulnerability — OSGeo GeoServer GeoTools contains an improper neutralization of directives in dynamically evaluated code vulnerability due to unsafely evaluating property names as XPath expressions. This allows unauthenticated attackers to conduct remote code execution via specially crafted input. Listed in the CISA KEV catalog (added 2024-07-15) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~100%. Treat it as real and prioritize remediation over triage.

    Remediation · TruePositive EditorialCurated

    Required action for OSGeo GeoServer: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. CISA set a federal remediation due date of 2024-08-05. After patching, verify the vulnerable path is no longer reachable before closing the finding.
