GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. The GeoServer security mechanism can perform an unchecked JNDI lookup, which in turn can be used to perform class deserialization and result in arbitrary code execution. The same can happen while configuring data stores with data sources located in JNDI, or while setting up the disk quota mechanism. In order to perform any of the above changes, the attack needs to have obtained admin rights and use either the GeoServer GUI, or its REST API. The lookups are going to be restricted in GeoServer 2.21.0, 2.20.4, 1.19.6. Users unable to upgrade should restrict access to the `geoserver/web` and `geoserver/rest` via a firewall and ensure that the GeoWebCache is not remotely accessible.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

According to its banner, the version of GeoServer running on the remote host is prior to 2.19.6 or 2.20.0 < 2.20.4. It is, therefore, affected by an Insecure Deserialization

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
