CVE-2023-25157: OGC Filter SQL Injection Vulnerabilities
GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. 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. Users are advised to upgrade to either version 2.21.4, or version 2.22.2 to resolve this issue. Users unable to upgrade should disable the PostGIS Datastore encode functions setting to mitigate strEndsWith, strStartsWith and PropertyIsLike misuse and enable the PostGIS DataStore preparedStatements setting to mitigate the FeatureId misuse.
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.
Workarounds
- 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).
- Enabling the PostGIS DataStore preparedStatements setting to mitigate the FeatureId vulnerability.
