GeoServer OGC Filter SQL Injection Vulnerabilities

Critical severity GitHub Reviewed Published Feb 21, 2023 in geoserver/geoserver • Updated Feb 22, 2023

Package

maven org.geoserver.community:gs-jdbcconfig (Maven)

Affected versions

< 2.21.4
>= 2.22.0, < 2.22.2

Patched versions

2.21.4
2.22.2

Description

Impact

GeoServer includes support for the OGC Filter expression language and the OGC Common Query Language (CQL) as part of the Web Feature Service (WFS) and Web Map Service (WMS) protocols. CQL is also supported through the Web Coverage Service (WCS) protocol for ImageMosaic coverages.

SQL Injection Vulnerabilities have been found with:

  • PropertyIsLike filter, when used with a String field and any database DataStore, or with a PostGIS DataStore with encode functions enabled
  • strEndsWith function, when used with a PostGIS DataStore with encode functions enabled
  • strStartsWith function, when used with a PostGIS DataStore with encode functions enabled
  • FeatureId filter, when used with any database table having a String primary key column and when prepared statements are disabled
  • jsonArrayContains function, when used with a String or JSON field and with a PostGIS or Oracle DataStore (GeoServer 2.22.0+ only)
  • DWithin filter, when used with an Oracle DataStore

Patches

  • GeoSever 2.21.4
  • GeoServer 2.22.2
  • GeoServer 2.20.7
  • GeoServer 2.19.7
  • GeoServer 2.18.7

Workarounds

  1. Disabling the PostGIS Datastore encode functions setting to mitigate strEndsWith, strStartsWith vulnerabilities (Like filters have no mitigation, if there is a string field in the feature type published).
  2. Enabling the PostGIS DataStore preparedStatements setting to mitigate the FeatureId vulnerability.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
