Advisories for Maven/Org.geoserver/Gs-Main package

A GeoServer that uses ENTITY_RESOLUTION_ALLOWLIST may allow attacker to perform unauthenticated Server-Side Request Forgery (SSRF).

GeoServer's Server Status page and REST API (at /geoserver/rest/about/status) lists all environment variables and Java properties to any GeoServer user with administrative rights as part of those modules' status message. These variables/properties can also contain sensitive information, such as database passwords or API keys/tokens, for example: Data stores defined with parameterized catalog settings (-DALLOW_ENV_PARAMETRIZATION=true) which need a password or access key. GeoServer's official Docker image uses environment variables to configure …

A stored cross-site scripting (XSS) vulnerability exists that enables an authenticated administrator with workspace-level privileges to store a JavaScript payload in uploaded style/legend resources or in a specially crafted datastore file that will execute in the context of another user's browser when viewed in the Style Publisher. Access to the Style Publisher is available to all users although data security may limit users' ability to trigger the XSS.

This vulnerability requires GeoServer Administrator with access to the admin console to misconfigured the Global Settings for log file location to an arbitrary location. This can be used to read files via the admin console GeoServer Logs page. It is also possible to leverage RCE or cause denial of service by overwriting key GeoServer files.

Withdrawn This advisory has been withdrawn as there the effects of the bug would only give the caller an incomplete view of data which they would be authorized to see. Original Advisory PartialBufferOutputStream2 in GeoServer before 1.6.1 and 1.7.0-beta1 attempts to flush buffer contents even when it is handling an "in memory buffer," which prevents the reporting of a service exception, with unknown impact and attack vectors.

GeoServer through 2.18.5 and 2.19.x through 2.19.2 allows SSRF via the option for setting a proxy host.

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 …
