CVE-2023-28442: Geoserver for GeoNode sensitive information leak

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.64% (FIRST EPSS); higher than 50.6% 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.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.
  • Severity is disputed: the assigning authority (CNA) scores it 7.5, NVD 5.3.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

GeoNode is an open source platform that facilitates the creation, sharing, and collaborative use of geospatial data. Prior to versions 2.20.6, 2.19.6, and 2.18.7, anonymous users can obtain sensitive information about GeoNode configurations from the response of the `/geoserver/rest/about/status` Geoserver REST API endpoint. The Geoserver endpoint is secured by default, but the configuration of Geoserver for GeoNode opens a list of REST endpoints to support some of its public-facing services. The vulnerability impacts both GeoNode 3 and GeoNode 4 instances. Geoserver security configuration is provided by `geoserver-geonode-ext`. A patch for 2.20.7 has been released which blocks access to the affected endpoint. The patch has been backported to branches 2.20.6, 2.19.7, 2.19.6, and 2.18.7. All the published artifacts and Docker images have been updated accordingly. A more advanced patch has been applied to the master and development versions, which require some changes to GeoNode code. They will be available with the next 4.1.0 release. The patched configuration only has an effect on new deployments. For existing setups, the patch must be applied manually inside the Geoserver data directory. The patched file must replace the existing `<geoserver_datadir>/security/rest.properties` file.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
