Product | Affected Versions

GeoServer | < 2.25.7 GeoServer | < 2.26.3 GeoServer | < 2.27.0 How the Exploit Works

The vulnerability is exploited by sending malicious Jiffle scripts to GeoServer. These scripts can be executed either as a rendering transformation in WMS dynamic styles or as a WPS process. Once executed, the malicious script enters an infinite loop, effectively triggering a denial of service attack on the GeoServer.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. In this instance, a malicious Jiffle script is sent to the GeoServer via an HTTP POST request:

POST /geoserver/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "jiffle_script": "while(true) {}" }

The script `while(true) {}` will run indefinitely, consuming resources and eventually leading to a denial of service.

Mitigation Guidance

To safeguard against this vulnerability, users are advised to either apply the vendor patch (GeoServer versions 2.27.0, 2.26.3, or 2.25.7) or disable WMS dynamic styling and the Jiffle process. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation.
